Answer:

90 degrees because A is an acute angle so x equals 45 degrees and so I multiply that by 2

Step-by-step explanation:

So the right angle is equal to 90° and the rest is unknown.

using the triangle sim theorem, which states that all interior angles are equal to 180°.

so it would be x+2x+90°=180°.

then you would need to simply which is 3x+90°=180°

subtract 90° from both sides and get 3x=90°

and then divide both sides by 3 which is 30°

then you would need to find the angle of B which is 2x so you would need to substitute 30° for x which is 60°

the answer is 60°

The measure of angle C is 20.5 angles C and D are complementary angles Find m
Kobotan [32]

Answer:

69.5 if C and D both add up to 90, M=90 if both angles C and D were complementary to combine to a supplementary.

Step-by-step explanation:

You're trying to find m which is a variable for measurement for the "D" angle.

Info Given:

20.5 for angle C

Unknown for angle D

Both angles are Complementary.

_____________________________________________

I have 2 answers for this (The question was stated unclearly so I have 2 interpretations of this)

1st Answer:

If you're asking to solve for M but the C and D angles add up to 90 then do

90 - 20.5 = 69.5

2nd Answer:

We know that both angles are complementary which are 90-degree angles.

If we combine them then the angles add up to 180.

So C and D add up to form a Supplementary Angle.

20.5+69.5 + m = 180

Then M could possibly be 90.

Use the graph that shows the solution f(x) = G (x)
Bingel [31]

Answer:

The correct options are A and C.

Step-by-step explanation:

The given functions are

F(x)=-\frac{3}{4}x^2+3x+1

G(x)=2^x

We have to find to solution for the equation

F(x)=G(x)

-\frac{3}{4}x^2+3x+1=2^x

The solution of the above equation is the intersection of F(x) and G(x).

From the graph it is noticed that both graph intersects each other at (0,1) and (2,4).

The x-coordinates of these points are the solutions of the given equation.

Therefore the solution of given equation are 0 and 2.

Therefore option A and C are correct.
