Answer:
28 (c)
Step-by-step explanation:
26+(3*28)+(2*28+14)=180
all of the angles in every triangle must add up to 180 degrees
Answer:
divide both sides by 2 (to isolate the equation in parenthesis)
subtract 3 from both sides (to isolate the variable x)
x=1
Step-by-step explanation:

Answer:
Step-by-step explanation:
From the given right angle triangle,
The unknown side represents the hypotenuse of the right angle triangle.
With m∠x as the reference angle,
the adjacent side of the right angle triangle is 7.8
the opposite side of the right angle triangle is 8
To determine m∠x, we would apply
the Tangent trigonometric ratio.
Tan θ, = opposite side/adjacent side. Therefore,
Tan x = 8/7.8 = 1.026
x = Tan^-1(1.026)
x = 45.7° to the nearest tenth
Short Answer:
x = 150
y = 120
z = 30
Long Answer:
x (exterior angle theorem) -> 95+55= 150
y (linear pair theorem/supplementary angles)-> 180-55= 120
z (linear pair theorem/supplementary angles) -> 180-150=30
Hope this helps
