Answer:
x = 20
Step-by-step explanation:
The indicated angles are vertical and therefore congruent, hence
6x - 10 = 3x + 50 ( subtract 3x from both sides )
3x - 10 = 50 ( add 10 to both sides )
3x = 60 ( divide both sides by 3 )
x = 20
Divide by the constant on the right to put the equation into intercept form.
.. -3x/8 +4y/8 = 1
.. x/(-8/3) +y/2 = 1
The intercepts are (-8/3, 0) and (0, 2).
Answer:
b) The measure of angle B is 117°.
Step-by-step explanation:
Angles A and C are vertical angles, so are congruent. Angles C and 27° total 90°, so ...
∠C = 90° -27° = 63° . . . . . not 53°
The measure of angle B is the supplement of angle A or C, so is ...
∠B = 180° -∠C = 180° -63°
∠B = 117°
Only choice B is correct.
