One angle of an isosceles triangle measures 40°. Which other angles could be in that isosceles triangle? Choose all that apply.

V125BC [204]

70°

(the sum of the angles of a triangle is 180°

180 - 40 = 140.

140/2 = 70

The other 2 angles are 70°

70° + 70° + 40° = 180°).

What is the image of the point (2, -3) after a rotation of 180° counterclockwise

horsena [70]

Answer:

(-2, 3)

Step-by-step explanation:

When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative

Point (2, -3) becomes:

Point (-2, 3)

Angles A and B are complementary. Angle A has a measure of 2X - 8. Angle B

harkovskaia [24]

Answer:

Step-by-step explanation:

180 = 2x-8 + 36

152 = 2x

76 = x

now plug it into the given expression

∠A = 2x-8

∠A = 2(76) -8

∠A = 152-8

∠A = 144 °

Evaluate the function. f(x) = -4x^2+9Find f(-3)

svetlana [45]

Answer:

$f(-3)=-27$

Step-by-step explanation:

So we have the function:

$f(x)=-4x^2+9$

And we want to find f(-3).

So, let's substitute -3 for x. Therefore:

$f(-3)=-4(-3)^2+9$

Square:

$f(-3)=-4(9)+9$

Multiply:

$f(-3)=-36+9$

Add:

$f(-3)=-27$

And we're done!
