Start with an equation summing all the angles in this triangle:
180 = <M + <N + <P
we are given <M and <N but not <P. But, since MN=NP, the angle <P is the same as the angle <M (isosceles, make a drawing to see). So
180 = 2<M + <N
180 = 2(3x+1) + x-11
180 = 7x - 9
x = 27
<P = 3*27+1 = 82 degrees
Answer:
B
Step-by-step explanation:
The first term has a power and the second term doesnt have a power.
Hope it helped. Pls mark me as brainliest.
We are given expression: 
Let us distribute 3/8 over exponents in parenthesis, we get


We can get x and y out of the radical because, we get whlole number 1 for x and y exponents for the mixed fractions.
So, we could write it as.

Now, we could write inside expression of parenthesis in radical form.
![xy\sqrt[8]{2x^{3}x^4y^7}](https://tex.z-dn.net/?f=xy%5Csqrt%5B8%5D%7B2x%5E%7B3%7Dx%5E4y%5E7%7D)
Z=1/5
Subtract 85 from both sides which gets you 25z=5.
Divide both sides by 25 which is z=5/25
Simplify which gives us the answer z=1/5.
