X + 20 + x + 40 + 2x + 2x = 360 degrees. This is because all exterior angles add up to 360. You then simplify and you have 6x+60=360 and then subtract 60 from both sides so you get 6x=300. Divide by 6 on both sides giving you x= 50.

Find the value of t, rounded to the nearest tenth
sergij07 [2.7K]

<u>Given</u>:

Given that RST is a right triangle.

The measure of ∠R is 35°.

The length of ST is 12 units.

The length of the hypotenuse is t units.

We need to determine the value of t.

<u>Value of t:</u>

The value of t can be determined using the trigonometric ratio.

Thus, we have;

sin \ \theta=\frac{opp}{hyp}

where \theta=R, the side opposite to ∠R is ST and hypotenuse is SR.

Substituting these values, we get;

sin \ R=\frac{ST}{SR}

Substituting ST = 12 and SR = t, we get;

sin \ 35^{\circ}=\frac{12}{t}

Simplifying, we get;

t=\frac{12}{sin \ 35^{\circ}}

t=\frac{12}{0.574}

t=20.9

Thus, the value of t is 20.9 units.

What 60% of what number is 80? How do I figure this out?
Fudgin [204]
80 is 60% of 133.333 repeating, or rounded to 133.  You can find this by doing 80 / 60 = 1.333 repeating.  Then, you would do 1.333 x 100 = 133.333 repeating.

Find the least common multiple of 3 and 5:

3: 3,6, 9,12,15,18,21

5: 5, 10, 15, 20

The least common multiple is 15. This means every 15 days they will be the same day.

Add 15 days to May 5:

5 + 15 = 20

The next day would be May 20
