If AC=18x-7,find the x. Round to the nearest hundredth if necessary <br>AB=7x+29 <br>BC=30

Margaret [11]

Answer:

$x=6$

Step-by-step explanation:

AC = AB + BC

$18x-7=(7x+29)+30$

$18x-7=7x+29+30$

$18x-7=7x+59$

Add 7 to both sides:

$18x-7+7=7x+59+7$

$18x=7x+66$

Subtract 7x from both sides:

$11x=66$

Divide both sides by 11:

$\frac{11x}{11}=\frac{66}{11}$

$x=6$

Moira said, "If a right triangle has one side with a length of 3 units and one side with a length

Dima020 [189]

If the two sides with length 3 and 4 are the two legs, then the missing side, i.e. the hypotenuse, is indeed 5.

But it could also be the case that 4 is the hypotenuse and 3 is one of the legs. In this case, the missing side is the other leg, so we calculate it using

$\sqrt{4^2-3^2}=\sqrt{16-9}=\sqrt{7}$

So, a right triangle with legs $\sqrt{7}$ and 3 has an hypotenuse of 4.

Need some help on vertical adjacent complementary angles (algebraic)

dusya [7]

Step-by-step explanation:

$(2c + 8) + (6c - 6) = 90 \\ 8c + 2 = 90 \\ 8c = 88 \\ c = \frac{88}{8} = 11$
