Answer: 12
Step-by-step explanation:
Answer:
N = Q/3 - V
Step-by-step explanation:
Q = 2N + 3V solve for N
Subtract 3V from both sides
Q - 3V = 3N
Divide both sides by 3
(Q - 3V)/3 = N
Q/3 - V = N
or
N = Q/3 - V
Answer:
Step-by-step explanation:
by inspection
angles 2 and 3 are equal, so they will be half angle ABC
angles 1 and 5 are equal so they will be
angle 1 + angle 5 + angleABC = 180° kind of a rule for triangle
the sum of all angles - 180°
(angle 1) x 2 = 180° - 70°
angle 1 = 90° - 35°
angle 1 = 55° which equals angle 5
angle 4 is clearly a right angle 90°
DO the same procedure for the bottom triangle
angle 8 and 9 are half of angle ADC
angle 8 and 9 are half of 46°
both are 23°
angle 6 equals angle 7
2 ×angle 6 = 180° - 46°
angle 6 = 90° - 23°
angle 6 = 67° angle 7 = 67°
Did I find them all
