Answer:
58.1 and 31.9 degrees
Step-by-step explanation:
x + other angle = 90 because complementary angles add up to 90
x = the angle
x = 26.2 more than the other angle
subtract 26.2 from both sides
x - 26.2 = other angle
x + other angle = 90
plug x - 26.2 for other angle
x + (x-26.2) = 90
2x - 26.2 = 90
add 26.2 to both sides to isolate the variable and its coefficient
2x = 116.2
divide both sides by 2 to find x
x = 58.1
other angle = x - 26.2 = 31.9

Answer:
You have to find the are of the triangle: Area=(base* height)/2=
=(10x + 2y)*(3x - y)/2=(5x + y)*(3x - y)=
=15x2-2xy-y2.
Answer:
A. 45
- as AB and CD are parallel to each other, the value of y will be equal to 45° in CD
