Find x
To solve for x, we make use of:
16. 9
Since each side are congruent, you set the two sides to each other
7x-12=3x
Subtract 7x from both sides
-12=-4x
Divide -4 from both sides
3=x
3+3+3=9
18. 28
2x-3=3x-10
Add 10 on both sides
2x+7=3x
Subtract 2x on both sides
7=x
7+7+7+7=28
Answer:
70
Step-by-step explanation:
Answer:
∠a and ∠d; ∠b and ∠c
Step-by-step explanation:
The two triangles as similar triangles and the scale factor is 2 : 1
The sides measuring 6 and 3 are corresponding sides
The sides measeuring 8 and 4 are ocrreposnding sides
⇒ ∠a and ∠d are corresponding angles
The sides measuring 8 and 4 are corresponding sides
The sides measeuring 4 and 2 are ocrreposnding sides
⇒ ∠b and ∠c are corresponding angles
Do you need to factor? solve for x?
