Answer:

30°

Step-by-step explanation:

Suppose smaller angle = x°

larger angle = (2x+90) deg

Supplementary angles so sum = 180 degree

x+2x+90=180

3x+90=180

3x=180-90

3x=90

x=30

larger angle =2x+78=68+78=146 degree

Smaller angle = 30°

Hope this answer helps you :)

Answer:

30, 150

A + B = 180

A = 2B+ 90

2B + 90 + B = 180

3B = 90

B=30 A=150

Vikki [24]

Where 1/3 of the 1 section had been painted, have each section have 3 parts. So each complete section will be 3/3. Where there is 4 section with 3 parts each, we have 12 parts. Thus, you painted 1/12 of the fence.

Find the measure of each bolded arc. Round to the nearest hundredth

vladimir1956 [14]

Answer:

Arc Length = 68.7

Step-by-step explanation:

The formula that is used to find the arc length:

s = (θ/360) * 2πr

(You would get the value of θ, by subtracting 57 from 360)

(You would get r by dividing 26 by 2)

Now we can solve this;

s = (303/360) 2π(13)

s = 0.842 * 2π(13)

s = 0.842 * 0.283(13)

s = 68.7

Hope this helps!

Yao Xin puts 3/10 liters of potting soil in each pot for planting flowers. She has 17/3 liters of potting soil. How many pots ca

kari74 [83]

For this case defining variables we have:

x: total amount of liters of potting soil.

y: number of liters of potting soil in each pot.

We have then to find the number of pots we use the following expression:

$N = \frac{x}{y}$

Substituting values we have:

$N = \frac{\frac{17}{3}}{\frac{3}{10}}$

Rewriting we have:

$N = \frac{170}{9}$

$N = 18.8$

Rounding to the previous whole we have:

$N = 18$

Answer:

Yao Xin can fill 18 pots

What is StartFraction one-half EndFraction x is less than or equal to 18.x ≤ 18

Eduardwww [97]

Answer:

$x\leq 36$

The solution for $x$ is all real numbers less that or equal to 36.

Step-by-step explanation:

Given expression:

$\frac{1}{2}x\leq18$

To find the solution for $x$

Solution:

In order to solve for $x$ , we will make sure to isolate the unknown variable $x$ on left side alone by doing math operations on both sides of the inequality.

We have:

$\frac{1}{2}x\leq18$

Multiplying both sides by 2.

$2.\frac{1}{2}x\leq18\times 2$

The 2 on left side will cancel each other leaving $x$ alone.

Thus, we have:

$x\leq 36$

Thus, solution for $x$ is all real numbers less that or equal to 36.
