3 is a factor of 12 and 75 so
12/75 = 4/25
Hello from MrBillDoesMath!
Answer:
96 degrees
Discussion:
The base angles of an isosceles triangle are equal and a triangle has 180 degrees. In our case this means that
42 + 42 + (measure of vertex angle) = 180
84 + (measure of vertex angle) = 180 => (subtract 84 from both sides)
84 - 84 + (measure of vertex angle) = 180- 84 =>
(measure of vertex angle) = 180- 84 = 96
Thank you,

Answer:
hope it helps plz mark me brainliest!
Step-by-step explanation:
Point, slope form: [y-y1=m(x-x1)]
y-4=2(x-1)
Distribute:
y-4=2x-2
Add 4 on both sides
y=2x+2
There's your answer.
The mountain climber's ascent rate is calculated by dividing 3/4 kilometer by 1/12 of an hour. That is mathematically expressed as,
ascent rate = (3/4 km) / (1/12 h)
= 9 km/h
Thus, the climber ascended at a rate of 9 km/h.
No because it's negative 20 plus positive 40 So it's 20 percent more than the original
