Answer:
Step-by-step explanation:
N = 3rt^4 - 5rz
now factor r out
N = r(3t^4-5z)
divide by r on both sides
N/r = (3t^4 - 5z)
subtract (3t^4)
N/r - 3t^4 = -5z
now divide by -5 to isolate the variable (z)
= z

Tbh idk all I got was 51.496 I’m dumb i just want points ^_^
A). They are not similar, because 6/13 is not equal to 8/20
For triangles to be similar, the ratios of sides need to be the same (shortest to shortest, middle to middle, longest to longest). The shortest sides are 6 and 13, respectively, the middle ones are 8 and 20. Because 6/13 is not equal to 8/20, the triangles are not similar.
Answer:
ABC = 65
Step-by-step explanation:
The sum of the angles of a quadrilateral are 360
2x-15 + x + 2x-15 +x = 360
Combine like terms
6x -30 = 360
Add 30 to each side
6x -30 +30 = 360+30
6x= 390
Divide by 6
6x/6 = 390/6
x=65
We want angle ABC
ABC = x
ABC = 65
