The triangle has no obtuse angles.
Obtuse angles are greater than 90 degrees, or are wider than a right angle. These are all acute angles in this diagram because they are all less than 90 degrees.
Answer:
B is the correct answer
Step-by-step explanation:
Angles 1, 2, and 3 added together should make 180 degrees.
So, if angle 2 is 70 degrees, you subtract 70 from 180 (180-70=110) and you're left with 110 degrees.
Angle 1 and 3 add together should make 110 degrees which makes B the only true statement.
The correct answer is ''b'' because 3/4 is 6/8 and 7/8 is 7/8 so also is 6/7 i hope it helped u
There are two possible ways for X=1: first light is green and second is red OR first light is red and second is green. The probabilities for these two options are to be summed: 0.6*0.4 + 0.4*0.6 to give the probability of exactly one light being green, namely 0.48.
