Help i need to understand
mote1985 [20]
Using thereoms/postulates, we know that the 60° angle and the (5z - 85)° angle are congruent

so to first find z..
60 = 5z - 85
145 = 5z
29 = z

now that we know z, we can find x
simply replace the z in (5z - 85) with 29
and add the entire angle to x to equal 180
(supplementary angles)
(5(29) - 85) + x = 180
(145 - 85) + x = 185
60 + x = 185
x = 125


x = 125 \\ z = 29

PLEASE HELP WITH #14 AND #7 PLEASE A.S.A.P !!!

Answer:

7.) 16.7

Step-by-step explanation:

7). First you have to find the length of the line with the triangle that is at a 90 angle with the longest side of the triangle

Using the pythagrorem theorem a² + b² = c²

4² + b² = 5²

b² = 5² - 4²

b² = 25 - 16

b² = 9

√b² =√9

b = 3

next you do the same thing to find the missing segment of the longest side

3² + b² = 13²

b² = 169 - 9

b² = 160

b = √160 or  ≈ 12.7

12.7 + 4 = 16.7

so 16.7 is the length of that side
