Answer:

Step-by-step explanation:

SV = RV

2x+2 = 10

x = 4

r² = RV² + VZ² = 10²+7.5² = 156.25

UZ = √[r²- (QR/2)²] = √[156.25 - 10²] = √56.25 = 7.5

In the diagram below segment DEF is shown(since all three letters are shown, they are collinear). If DE=3x+2, EF= x+5, and DF= 2
amm1812

The value of x is 4.

By Geometry, we know that line segment DF = DE + EF, which is equivalent to:

DF = 3\cdot x + 2 + x + 5

DF = 4\cdot x + 7 (1)

Now we solve algebraically the resulting expression.

If we know that DF = 23, then we solve the equation for x:

4\cdot x + 7 = 23

4\cdot x = 16

x = 4

The value of x is 4.
