Answer:
y = 5
Step-by-step explanation:
Since this is an isosceles triangle, Angle B and Angle C are equivalent. We can use this to find x
3x = 75
x = 25
Angles in a triangle add up to 180, so knowing the measure of Angle B and Angle C, we can find the measure of Angle A
Angle A = 180-(75+75)
Angle A = 180-150
Angle A = 30
We know Angle A = 4y+10
4y + 10 = 30
4y = 20
y = 5
Answer:
45/58 it is already in simplest form
Step-by-step explanation:
Answer:
x=27
Step-by-step explanation:
The formula for the volume of a pyramid is L*W*H/3
We know all three, being x, x, and x/9
So after we plug those in, we see that x^3/27 = 27
then solving for x we get √27*27 which is 27
Please Vote me brainly, it really helps, and i hope i helped you.
We know that x > 2 ( or : x ≠ +/- 2 )
We have to factorize the numerator and the denominator:
x² - x - 6 = x² - 3 x + 2 x - 6 = x ( x - 3 ) + 2 ( x - 3 ) = ( x - 3 ) ( x + 2 )
x ² - 4 = ( x - 2 ) ( x + 2 )
Answer:
m =-1.25
Step-by-step explanation:
5.2m + 5 = 2.9m – 3 – 4.1m
Combine like terms
5.2m + 5 = -1.2m – 3
Add 1.2m to each side
5.2m +1.2m +5 = -1.2m +1.2m -3
6.4m +5 = -3
Subtract 5 from each side
6.4m +5-5 = -3-5
6.4m = -8
Divide each side
6.4m/6.4 = -8/6.4
m =-1.25
