Answer:
<A=143
Step-by-step explanation:
<A=<B (corresponding angles)
7x+24=3x+92
7x-3x=92-24
4x=68
dividing both sides by 4
x=17
Now <A=7x+24
<A=7(17)+24
<A=119+24
<A=143

Answer:
9
Step-by-step explanation:
The two triangles  .
.
Therefore the corresponding sides are proportional.

From the diagram |MP|=4, |PN|=3, |MN|=5 |ST|=x and |TR|=12.
Let us substitute the values and solve for x.

Multiply both sides by 3 to get:

This implies that:

Therefore x=9
 
        
             
        
        
        
Answer:
<u>The correct answer is C. 21x³y</u>
Step-by-step explanation:
Let's simplify the product, this way:
(49x²y)^1/2 * (27x⁶y^3/2)^1/3
Let's recall that x^1/2 = √x and  x^1/3 = ∛x
√(49x²y) * ∛(27x⁶y^3/2)
7x √y * 3x² √y
Let's recall that √y * √y = √y² = y
21x³y
<u>The correct answer is C. 21x³y</u>
