For question 6 what is that value of x? For question 7 find m

forsale [732]

(6) Given that in ΔPQR, m∠P = (x+14)°, m∠Q = (6x-12)° and m∠R = (3x+8)°

We need to determine the value of x.

Value of x:

By triangle sum property, we have;

$\angle P+\angle Q+\angle R=180^{\circ}$

Substituting the values, we get;

$x+14+6x-12+3x+8=180$

$10x+10=180$

$10x=170$

$x=17$

Thus, the value of x is 17

(7) Given that ΔGHI, m∠G = (4x+13)°, m∠H = (8x-52)° and m∠I = (2x+4)°

We need to determine the measure of ∠G

Value of x:

By triangle sum property, we have;

$\angle G+\angle H +\angle I=180$

Substituting the values, we get;

$4x+13+8x-5+2x+4=180$

$14x+12=180$

$14x=168$

$x=12$

Thus, the value of x is 12.

The measure of ∠G:

Substituting x = 12 in m∠G = (4x+13)°, we get;

$m\angle G=(4(12)+13)^{\circ}$

$m\angle G=(48+13)^{\circ}$

$m\angle G=61^{\circ}$

Thus, the measure of angle G is 61°

write a simplified polynomial expression in the standard form to represent the area of the rectangle below x-4 5x+2

Ann [662]

The area of the rectangle is $5x^{2} -18x-8$

Explanation:

One side of the rectangle is $x-4$

The another side of the rectangle is $5x+2$

The formula to find the area of the rectangle is length × width

Area = length × width

Substituting the values, we have,

$\begin{aligned}\text { Area } &=(x-4)(5 x+2) \\&=5 x^{2}+2 x-20 x-8 \\&=5 x^{2}-18 x-8\end{aligned}$

Thus, the area of the rectangle is $5x^{2} -18x-8$

240 is 60% of what number?

Brums [2.3K]

Hi there! To find the answer to that question, we can write and solve a proportion. Set it up like this: 240/x = 60/100. This is because we're looking for the whole and we already know the part, which is 240. Cross multiply the values in order to get 24,000 = 60x. Now, divide each side by 60 to isolate the variable. When you do, you get x = 400. You can check this by dividing and then multiplying that quotient by 100. 240/400 is 0.6 and 0.6 * 100 is 60. That makes 60%. There. 240 is 60% of 400.
