Answer:
56 deg
Step-by-step explanation:
All internal angles of a triangle add up to 180 degrees
hence,
∠O + ∠R + ∠F = 180
x + (x+43) + (x-31) = 180
x + x+43 + x -31 = 180
3x+ 12 = 180
3x = 180 - 12 = 168
x = 168/3 = 56 deg
The answer is x=-3 and y=13
Answer:
7⁵-3=7⁵x- 19
Step-by-step explanation:
16807 - 3 = 7⁵x - 19
16804 = 7⁵x - 19
16804 = 16807x - 1
adding 19 on both sides
16804 + 19 = 16807x - 19 + 19
16823 = 16807x
x = 16823 / 16807
16823 upon 16807 is the x
