Answer:

The measure of Angle A is 45.5 degrees

Step-by-step explanation:

In order to find the measure of the angle A, add it to the measures of angle B and C. Since it is an isosceles triangle, we know that B and C have the same measure. Then we set this equal to 180.

A + B + C = 180

2x + 4 + 3x + 5 + 3x + 5 = 180

8x + 14 = 180

8x = 166

x = 20.75

Now we can find the measure of Angle A by putting the value of x in for x.

2x + 4 = A

2(20.75) + 4 = A

41.5 + 4 = A

45.5 = A

Find the value of y when x equals 17 -x+y=-27
since x is equal to 17 you plug it in the equation as follows...
-17+y=-27
then you add 17 on both sides...
y=-27+17

Answer:

f(-2) = 0

f(1) = 12

f(2) = 5

Step-by-step explanation:

f(-2) will lie in the function f(x) =x^2 - 4

\therefore f( - 2) =  {( - 2)}^{2}  - 4 = 4 - 4 = 0

f(1) will lie in the function f(x) =2x^2 +10

\therefore f(1) = 2 {(1)}^{2}  + 10 = 2 + 10 = 12

f(2) will lie in the function f(x) =5

\therefore f(2) = 5
