Answer:
43+(x-7)=90
43+(x-7)-43=90-43
(x-7)=46
x-7+7=47+7
x=54
Step-by-step explanation:
Answer:
s = 11
Step-by-step explanation:
Given
= 22 ← substitute r = 242
= 22 ( multiply both sides by s )
242 = 22s ( divide both sides by 22 )
11 = s
I think it would be H tell me if it ain’t
Answer:
Correct choice is B
Step-by-step explanation:
In step 4 were proved that 
By definition, similar triangles have proportional lengths of corresponding sides. To the side AB corresponds side ED, to the side AC corresponds side DC and to the side BC corresponds side EC. Thus,
Answer:
C. m∠4 = m∠8
D. m∠2 = m∠7
Step-by-step explanation:
Here, we use the principles of alternate angles, corresponding angles and vertically opposite angles to confirm which of the statements are true. Alternate angles are always equal, corresponding angles are equal, likewise vertically opposite angles.
From the given question, it was given that a is parallel to b. Thus, it can be observed and deduced that;
m∠4 = m∠8 (corresponding angles)
and
m∠2 = m∠3 (vertically opposite angles)
m∠3 = m∠7 (corresponding angles)
So that,
m∠2 = m∠7
Thus in the question, statements C and D are true.
