Answer:
The measure of angle B is 41°.
Step-by-step explanation:
180 - 113 = 67.
67 + 72 = 139.
180 - 139 = 41.

The given triangle is a right triangle.
The tangent of an angle of right triangle is obtained by dividing the opposite side of the angle with the adjacent side of the angle.
The opposite side of angle R is 5 cm and the adjacent side of angle R is 12 cm.
tan R = 5 / 12 = 0.4167
R = arctan (0.4167) = 22.6 degrees.
Answer:
y = 3x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3, thus
y = 3x + c ← is the partial equation
To find c substitute (3, - 3) into the partial equation
- 3 = 9 + c ⇒ c = - 3 - 9 = - 12
y = 3x - 12 ← equation of line
-3.3=
Multiply both sides of the equation by 6 to isolate x.
-19.8=x
Your answer is -19.8.
