Answer:
x=30°
Step-by-step explanation:
To find the value of x we need atleast 2 other angles, and we do we have one 70, but we need to get another angle from the info given outside the triangle,
Notice, the angle beside 100 can be found by simply subtracting 180-100
(since angles are on a straight line [Supplementary angles]
So, the angle is 80
Now, we know that the angles inside a triangle add up to 180
So basically, to find x:
70+80+x = 180
150+x = 180
x = 180-150
x=30°
Hoep this helps!
Mark brainliest if you think i helped! Would really appreciate!
Answer:
adjacent and complementary angles
Step-by-step explanation:
we know that
If the sum of two angles is equal to then, the angles are Complementary
and
Two angles are Adjacent when they have a common side and a common vertex
In this problem we have
-----> by complementary angles
and
m<1 and m<4 have a common side and a common vertex
therefore
m<1 and m<4 are adjacent and complementary angles
Answer:
x = 51
Step-by-step explanation:
-17 = x/-3
Multiply each side by -3
-3 * -17 = x / -3 * -3
51 = x
