drek231 [11]

Answer:

Option C: 4

Step-by-step explanation:

<u>Use the Pythagorean Theorem:</u>

$a^2+b^2=c^2$

$3^2+b^2=5^2$

$9+b^2=25$

$b^2=16$

$b=4$

Therefore, the value of x is 4.

ABC is isosceles. A=48 degrees and B=4x+4, solve for X

Alchen [17]

Answer:

x=15.5

Step-by-step explanation:

since ABC is isosceles two sides should be equal

A=48

B=4x+4 , since 2 sides should be equal B and C are equal

therefore C is also equal to 4x+4

ADD ALL:

48+4x+4+4x+4=180

48+8x+8=180

8x+56=180

Transpose 56 so its gonna be (-56)

8x=180-56

8x=124

DIVIDE BY 8:

x=15.5
