Answer:

Step-by-step explanation:
(triangle)
(semicircle)
Add both together

Answer:
Perimeter: 310 units
Step-by-step explanation:
If x=4 and y=5, then the measure of the lengths would be..
8y+19= 8(5)+19= 59
8x+64= 8(4)+64= 96
13y-6= 13(5)-6= 59
16x+32= 16(4)+32= 96
To check if all these measurements are congruent, we can see if they match up with the measure of their parallel line, which they do in this case because 59=59
96=96
To find the perimeter of any shape, we add all the side lengths together
59+59+96+96= 310

Step-by-step explanation:
substitute x for the unknown number
Answer:
For the first question(B)
x=-2
x=5
For part C, the question is not clear
For the last question, the approximated value is -5/4
Answer:
<A = 27 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
Tan A = opp side / adj side
Tan A = 2/4
Tan A = 1/2
Taking the inverse tan of each side
tan^-1 ( tan A) = tan ^-1 (1/2)
A =26.56505118
Rounding to the nearest degree
A = 27
