Triangle RMN and Triangle RQP
Triangle JHL and TriangleLKJ
A=65 b=x c=x
so the equation is
65 + 2x =180
so you (-) 65 on both sides of the (=) sign
so 180-65=115
so now the equation is
2x=115
so you divide by 2
the answer is
57.5
Answer:
A
Step-by-step explanation:
Answer:
CNBD
Step-by-step explanation:
From the diagram, we can see that:

Then by Alternate Interior Angles:

From vertical angles, we also know that:

This is all we can gather from the given image. Knowing only three pairs of angles cannot prove congruence, as proving congruence requires at least one side.
Congruence cannot be determined.
To work out the probability of both errors occuring, simply multiply the probability of the first error by the probability of the second error. Therefore the probability of both errors occurring is 0.2 * 0.3 = 0.06.
