Answer:
D=E (Base angle of isosceles triangle are equal)
D+E+F= 180° (sum of angles of a triangle️)
(4x+7)+(4x+7)+(5x+10) = 180
13x = 180- 24
x= 156/13 = 12°
so, E= 4x+7 = 4×12+7 = 55
Hope this helps:)
Answer:
D,G
Step-by-step explanation:
linear function can be written in the form y=mx+b
Answer:
x=1.55
Step-by-step explanation:
42x-1=64
+1 +1
42x= 65
/42 /42
x= 1.55 (rounded)
Answer: X=55/2
Explanation: Set all the values equal to 180 since all the angles in a triangle equal to 180 degrees. I checked my answer with calculator!
