Angles ABC and CBD are complementary - they add up to 90°. This means
(4x + 52°) + (8x - 10°) = 90°
Solve for x :
12x + 42° = 90°
12x = 48°
x = 4°
It follows that angle CBD has measure
4 • 4° + 52° = 16° + 52° = 68°

Answer:
7/10
Step-by-step explanation:
7 at the top, 10 at the bottom
Remember
a(b+c)=ab+ac
and you can do ANYTTHING to be
L=5B
divide both sides by 5
L/5=B
sub L/5 for B in other equation
L+7=3((L/5)+7)
distribute
L+7=(3L)/5+21
minus 7 both sides
L=(3L)/5+14
time boths sides by 5
5L=3L+70
minus 3L both sides
2L=70
divide 2
L=35
