3/8 would be the correct slope, so D. He did not make a mistake. That is the correct slope.
Hey I’m sure it’s 4! Sorry if I’m wrong that’s quite confusing
1320 ft out of a mile. 5280 feet in a mile so
1320/5280
keep simplifying until you get to 1/4
Answer:
angle A = 18°
angle B = 36 + 3(18) = 90°
angle C = 54 + 18 = 72°
Step-by-step explanation:
A triangle is a shape with 3 sides. The total angle of a triangle is 180°. This means the sum of all the angle is 180°.
Let
angle A = a
angle B = 36 + 3a
angle C = 54 + a
The sum of angle A, B and C should be equals to 180°. Therefore,
a + 36 + 3a + 54 + a = 180°
collect like terms
5a + 90 = 180
5a = 180 - 90
5a = 90
divide both sides by 5
a = 90/5
a = 18°
angle A = 18°
angle B = 36 + 3(18) = 90°
angle C = 54 + 18 = 72°
