G)
Angles on a straight line add to 180°;
According to this rule, we can formulate the following equation:
(2x + 4) + (x + 8) = 180
Now, just simplify and solve for x:
3x + 12 = 180
3x = 168
x = 56°

H)
What is shown on the diagram are sometimes called C-angles;
They also add to 180°;
This C-angle rule is one of 3 that exist when you have a pair of parallel lines (in this case the two horizontal ones) and one line passing through them both.
Using the C-angle rule, we can formulate the equation:
(3x + 9) + (2x - 4) = 180
Simplify and solve:
5x + 5 = 180
5x = 175
x = 35°

Answer: C

<u>Step-by-step explanation:</u>

∑ 8( $\frac{7}{3}$ )⁽ⁿ⁻¹⁾ from n = 1 to n = 5

n = 1 → 8( $\frac{7}{3}$ )⁽¹⁻¹⁾

= 8 = $\frac{648}{81}$

n = 2 → 8( $\frac{7}{3}$ )⁽²⁻¹⁾

= $\frac{56}{3}$ = $\frac{1512}{81}$

n = 3 → 8( $\frac{7}{3}$ )⁽³⁻¹⁾

= $\frac{392}{9}$ = $\frac{3528}{81}$

n = 4 → 8( $\frac{7}{3}$ )⁽⁴⁻¹⁾

= $\frac{2744}{27}$ = $\frac{8232}{81}$

n = 5 → 8( $\frac{7}{3}$ )⁽⁵⁻¹⁾

= $\frac{19208}{81}$ = $\frac{19208}{81}$

Sum = $\frac{33128}{81}$

= 408.99

99 POINT QUESTION, AND BRAINLIEST!!!

77julia77 [94]

$\displaystyle\int_{x=1}^{x=14}\frac{1-\cos4x}{4x-\sin4x}\,\mathrm dx$

First, replace $y=4x$ and $\mathrm du=4\,\mathrm dx$ . Then you have

$\displaystyle\frac14\int_{y=4}^{y=56}\frac{1-\cos y}{y-\sin y}\,\mathrm dy$

If we take $z=y-\sin y$ , then immediately we see a differential in the numerator in the form of $\mathrm dz=(1-\cos y)\,\mathrm dy$ . So the integral becomes

$\displaystyle\frac14\int_{z=4-\sin4}^{z=56-\sin56}\frac{\mathrm dz}z$

and evaluates to

$\dfrac14\ln|z|\bigg|_{z=4-\sin4}^{z=56-\sin56}=\dfrac14\left(\ln|56-\sin56|-\ln|4-\sin4|\right)=\dfrac14\ln\left|\dfrac{56-\sin56}{4-\sin4}\right|$

making (A) the correct answer.
