Answer:
Step-by-step explanation: An acute triangle is a triangle that has all the measures of its angles to be less than 90° i.e none of the angles is greater than 90°
Since of angles in a triangle is 180, hence <A + <B + <C = 180
Given
<B = 50
50 + <A + <C = 180°
<A + <C = 180-50
<A + <C = 130°
Note that all the angles of an acute triangle are also different
Hence the possible values of A and C are 60° and 70° (since their sum must give is 130°)
Another possible values are 55° and 75°
Answer:
180
Step-by-step explanation: An acute triangle is a triangle that has all the measures of its angles to be less than 90° i.e none of the angles is greater than 90°
What is f(-3) for f(x)=2x^2-x+5?
A).11
B).17
C).20
D).26
Answer:
20
Step-by-step explanation:
f(x) = ((2 • 32) - 3) + 5
f(x) = ((2•32) - 3) + 5
f(x) = 20

Answer:
56°
Step-by-step explanation:
180°-139° = 41
180°-83°-41° = 56°
im bad at explaining bcuz eng is not my 1st language
Answer:
56 Deg.
Step-by-step explanation:
First, you need to use the Exterior Angles Theorem which states that the two opposite sides of a exterior angle add up to the exterior angle. So in this case,
83 + m<1 = 139
So then, you can do algebra and subtract 83 from both sides.
Then,
m<1 = 139 - 83
m<1 = 56 Degrees.

A line has a slope of 3 and passes through the point (4, 7). What is its equation in
slope-intercept form?
Answer:
Step-by-step explanation:
y - 7 = 3(x - 4)
y - 7 = 3x - 12
y = 3x - 5
The equation of the line in slope intercept form having slope 3 and passing through the point (4, 7) is y = 3x - 5.
What is Slope?Slope of a line is the rise over the run of the given line. It is usually denoted by m.
In other words, Slope of a line can be calculated by finding the difference of the y coordinates divided by the difference of the x coordinates where x coordinate and y coordinate of two points are given.
Equation of a line in slope intercept form is given by
y = mx + c
where, m is the slope and c is the y- intercept.
Now y-intercept is the y-coordinate of the point where x = 0 or when the line touches the Y axis.
Here, m = 3
We have a point (x, y) = (4, 7)
Substituting these values in the equation,
7 = (3 × 4) + c
7 = 12 + c
c = 7 - 12
c = -5
Substituting m = 3 and c = -5,
y = 3x - 5
Hence, the equation of the line passing through the point (4, 7) and with a slope of 3 is y = 3x - 5.

Marcos deposited $500 into a 2.5-year simple interest account. He wants to earn $50 interest. What interest rate must the account pay?
The account must pay a 40 percent interest rate under Marcos.
A basic interest account is what?A loan's or deposit's initial principal serves as the foundation for simple interest.
Contrarily, compound interest is calculated based on both the principal amount and the interest that is accrued on it each period.
Simple interest is simpler to compute than compound interest because it is just applied to the principal.

how can I find the slope to this I need help
Answer:
Your slope is -1
Step-by-step explanation:
Find the change in x and the change in y and put it in change in y over change in x.
Δx = -1 - -2 = 1
Δy = -1 - 0 = -1
Slope = rise over run = Change in y over change in x = Δy/Δx = -1/1
Therefore the slope is -1/1 which is written as just -1
