Answer:

a. x = 8

b. m<B = 140

Step-by-step explanation:

m<A = m<B

40 = 5x

x = 8

m<A + m<B = 180

m<B = 180 - m<A

m<B = 180 - 40

m<B = 140

Answer:

The last one

Step-by-step explanation:

Hey There!

The Pythagorean Theorem states that

the two legs squared added together equal the hypotenuse square

we are given the two legs so to find the missing side we square them, then add them together

$1^2=1\\3^2=9\\9+1=10$

the missing side length equals

$\sqrt{10}$

hope this helps!
