Answer:
m<A is 60 degrees
m<B is 30 degrees
Step-by-step explanation:
As the problem says, the sum of m<A and m<B=90 degrees (m<A+m<B=90). The given measures are (5x+10) for <A and 3x for <B
we can substitute (5x+10) and 3x as <A and <B into the equation
so:
5x+10+3x=90
Combine like terms
8x+10=90
subtract 10 from both sides
8x=80
divide by 8
x=10
Now substitute as x
m<A: (5*10+10)=50+10=60 degrees
m<B: (3*10)=30 degrees
Hope this helps!
