Let's call our unknown angle x .
We know that the sum of the three interior angles of a triangle is 180°
This way,

We get that the third angle measures 29°
Answer:
Kadence Only
Step-by-step explanation:
The m is always the slope and the b is the y intercept
Answer:
60
Step-by-step explanation:
Of means multiply and is means equals
Let n be the unknown number
135% * n = 81
Change to decimal form
1.35 n = 81
Divide each side by 1.35
1.35n/1.35 = 81/1.35
n =60
Gradient (m) = change in y/change in x
-2-5/0–2 = 3.5
gradient (m) = 3.5
Now evaluate one of the coordinates and the gradient in the equation
y = mx + c
-2 = 3.5(0) + c
c = -2
so the answer is
y = 3.5x -2
