Answer:
angle: 71
x = -3
Step-by-step explanation:
step 1: 180-(55+54) = 71
step 2: x+74=71 (subtract 74 from both sides)
step 3: x=-3
step 4: -3+74=71
Answer:
<em><u>5</u></em>
Step-by-step explanation:
They do not have the common factor of x or y, so not them.
The GCF is 5, Both numbers can be divded by 5:
20x/5 = 4x
35y/5 = 7y
Answer: for a the answer is 140° and for b x=25°
Step-by-step explanation:
for a, when you have 2 parallel lines cut by a transversal,the corresponding angles are congruent. and the angle140 is congruent to the corresponding angle as they are vertical angles are congruent.
for b, angle x is congruent to the angle that is supplementary to 155 therefore 180-155=25°
54+x=12+3x
X=21 =number of classes
