Answer:
The measure of the missing side length = 45
Step-by-step explanation:
Pythagorean Theorem states: A² + B² = C²
28² + B² = 53²
784 + B² = 2809
B² = 2809 - 784
B² = 2025
B = 
B = 45
Therefore the measure of the missing side length = 45

Answer:
The measure of the smallest angle of the triangle is 40.
Step-by-step explanation:
A right triangle adds up to 180
x+15+2x+90=180
Combine like terms
3x+105=180
Subtract both sides by 105
3x+105=180
-105=-105
___________
3x=75 Divide by 3
x=25
Plug in 25 for x for equation expression
90=90
25+15=40
2(25)=50
Therefore for the smallest angle is 40
