The first one because an Isosceles Triangle has two angles that are the same degrees.
Answer:
<em><u>42</u></em>
Step-by-step explanation:
If you add 42+42+24+24= 132. If they are similar, then the other shape should be equal. So, 35+35+10+10= 90. Then you subtract 132-90= 42. So 42 is the missing amount that needs to be added to x.
Answer:
-21 = 6t
Step-by-step explanation:
3t - 7 = 5t
Subtract 3t from each side
3t-7-3t = 5t-3t
-7 = 2t
Multiply each side by 3 to get 6t
-7*3 = 2t*3
-21 = 6t
