Answer:
BCD= 15
Step-by-step explanation:
3x-15+?=180
3x=180
x=60
x=60
3(60)-15=180
180-15=165
Answer: x=17
Step-by-step explanation:(6x+x+4x)+(10+17-34)=180
we know this because triangles always equal 180o so the 3 angles equa; 180 so 187/11 + 17
The answer is = 28 …………….
Answer:
The answer is X=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x+8(x+2)=52
x+(8)(x)+(8)(2)=52(Distribute)
x+8x+16=52
(x+8x)+(16)=52(Combine Like Terms)
9x+16=52
9x+16=52
Step 2: Subtract 16 from both sides.
9x+16−16=52−16
9x=36
Step 3: Divide both sides by 9.
9x 9
=
36
/9
x=4
