Answer:
x = 120°
Step-by-step explanation:
In order to find the value of x, first you need to find the values for each angle in ΔQTS. ∠QTS is equal to 70°. In order to find ∠QST we need to do 180 - 50 - 70 = 60°. Because we know that ∠QST is 60°, we can do 180 - 60 to find x, and we get 120°
Answer:
x= 9,-2
Step-by-step explanation:
A ratio is a mathematical comparison of two numbers, based on division. For example, suppose you bring 2 scarves and 3 caps with you on a ski vacation. Here are a few ways to express the ratio of scarves to caps
The simplest way to work with a ratio is to turn it into a fraction. Be sure to keep the order the same: The first number goes on top of the fraction, and the second number goes on the bottom.
In practice, a ratio is most useful when used to set up a proportion — that is, an equation involving two ratios. Typically, a proportion looks like a word equation, as follows:
For example, suppose you know that both you and your friend Andrew brought the same proportion of scarves to caps. If you also know that Andrew brought 8 scarves, you can use this proportion to find out how many caps he brought. Just increase the terms of the fraction
<h2> </h2>
so that the numerator becomes 8. Do this in two steps:
As you can see, the ratio 8:12 is equivalent to the ratio 2:3 because the fractions
are equal. Therefore, Andrew brought 12 caps

3) adjacent
x = 180 - 34 = 146
4)adjacent
x = 90 - 74 = 16
6)supplementary
2x + 5 + 75 = 180
2x + 80 = 180
2x = 100
x = 50
