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 :)

Have a great day

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.
