The largest triangle and the triangle whose hypotenuse is x are similar. So:
(21 + 4)/x = x/4
Cross multiply:
x^2 = 100
x = 10
Your answer is incorrect. It should be 10, not 20.
Answer:
d) x = 2
Step-by-step explanation:
3(x - 6) + 3 = -9
<em>open the parenthesis</em>
3x - 18 + 3 = -9
3x - 15 = -9
<em>add 15 to both sides of the equation</em>
3x - 15 + 15 = - 9 + 15
3x = -9 + 15
3x = 6
<em>divide both sides by 3</em>
3x/3 = 6/3
x = 6/3
x = 2
Answer: x= 63, y= 27
Step-by-step explanation:
x and angle measure 117 are a linear pair. They sum to 180.
117+x= 180. Subtract 117 from both sides.
x = 63
Looking at the relationship of x and y, the diagram shows that the two together equal 90 degrees. Add the two together and set equal to 90.
63+y= 90. Subtract 63 from both sides.
y = 27
