Answer:
m∠B = 119°
Step-by-step explanation:
- the measure of c and 112 are on the straight angle and they are both equal 180°
c = 180 - 112 = 68
∠c = 68°
- the sum of the interior angles of a triangle is 180°
- the measure of third angle = the sum of the interior angles - the sum of two angles
a = 180 - (51 + 68) = 61
∠a = 61°
- the measure of 61 and b are on the straight angle and they are both equal 180°
b = 180 - 61 = 119
∠b = 119°
also you can go on other way
- an exterior angle of a triangle is equal to the sum of the opposite interior angles
51 + 68 = 119
Answer:
300+12x=$450
Step-by-step explanation:
Answer: 7 times 50 = 350
Step-by-step explanation:
100 divided by 2 is 50, so 7 multiplied by 50 is 350. Please make me brainliest
Step-by-step explanation:
if you meant
x²-36=5x:
x²-5x-36=0
(x-9)(x+4)=0
x = 9 and x = -4
you want the positive one, so 9
