Asap i dont understand this

To find m<3, we can use the angle sum of triangles, in which the addition all angles in a triangle must be equal to 180°.

In this case:

m<3 +52°+29° = 180°

m<3 + 81° = 180°

m<3 = 180°-81°

m<3 = 99°

To find m<4, we can use adjacent angles on a straight line, where the addition of angles on a straight line must be 180°.

In this case:

m<4 + 99° = 180°

m<4 = 180°-99°

m<4 = 81°

Therefore m<3 is 99° while m<4 is 81°.

Hope it helps!

the answer is 14ft

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
