Answer:
x = 21.52
Step-by-step explanation:
Given:
hypotenuse (That has to be found out)
Side adjacent to the given angle
and an angle,
Hence we can say that Cos ratio would be used;
Cos(28) = 19 / x
x = 19 / Cos(28)
x = 21.52
Hope this helps!
Answer:
-7
Step-by-step explanation:
add them together and that's it
Answer:
A
Step-by-step explanation:
As two angles are same which means 3rd also is equal which means aaa axiom
a x=12
the sum of angles in a triangle is 180
53+39+4+7x=180
96+7x=180
7x=86
x=84/7
x=12
b. sum of angles in a triangle is 180
5x+(6x-5)+75=180
5x+6x-5+75=180
11x+70=180
11x=180-70
11x=110
x=110/11
x=10
that's how to solve it
4 2/12 - 2 3/12 = 1 11/12
hope this helps ;)
