You know the hypotenuse and the relevant angle and x is adjacent to this
Cos?= adj/hyp
Cos45=x/ root6 |multiply both side by root 6 to get rid of fraction
root6 x cos45 = x
x = root 3
Answer:
x = 55, y = 70, z = 125
Step-by-step explanation:
125 and x are adjacent angles and are supplementary, then
x = 180 - 125 = 55
The triangle is isosceles ( 2 congruent sides ) thus the base angles are congruent, both 55
The sum of the 3 angles in the triangle = 180° , thus
y = 180 - (55 + 55) = 180 - 110 = 70
55 and z are adjacent and supplementary, so
z = 180 - 55 = 125
