Answer

Step-by-step explanation:

chord makes or arc make 120° at the center.

sum of other two angles of triangle=180-120=60

because they are equal.

so each angle=60/2=30°

tangent line makes angle 90° with radius .

so 30+y=90

y=90-30=60°

100 POINTS 10 QUESTIONS PLEASE HELP PICTURES BELOW PLEASE SPECIFY WHICH QUESTION YOU ARE ANSWERING

Semenov [28]

Answer:

The answers are $\frac{2}{5}, \frac{1}{4}, \frac{1}{10}, \frac{5}{2}, \frac{5}{8}, \frac{4}{1}, \frac{8}{5},$ and $\frac{10}{1}$ .

Step-by-step explanation:

Proportions are fractions that can be made by using the given numbers, which in this case are 2, 5, 8, and 20. Let's pair each one with the other three and then simplify if possible.

First, let's begin with 2:

$\frac{2}{5} = \frac{2}{5}$

$\frac{2}{8} = \frac{1}{4}$

$\frac{2}{20} = \frac{1}{10}$

Then, let's do 5:

$\frac{5}{2} = \frac{5}{2}$

$\frac{5}{8} = \frac{5}{8}$

$\frac{5}{20} = \frac{1}{4}$

Note that we already have $\frac{1}{4}$ , so we do not need to include an additional one.

Now, let us do 8:

$\frac{8}{2} = \frac{4}{1}$

$\frac{8}{5} = \frac{8}{5}$

$\frac{8}{20} = \frac{2}{5}$

See how we already have $\frac{2}{5}$ , so we won't have to include that as well.

Finally, let's do 20:

$\frac{20}{2} = \frac{10}{1}$

$\frac{20}{5} = \frac{4}{1}$

$\frac{20}{8} = \frac{5}{2}$

Now see that we already have both $\frac{4}{1}$ and $\frac{5}{2}$ , so we won't have to include both of them, as they are both extras.

Hence, the answers are $\frac{2}{5}, \frac{1}{4}, \frac{1}{10}, \frac{5}{2}, \frac{5}{8}, \frac{4}{1}, \frac{8}{5},$ and $\frac{10}{1}$ .

What number solves the equation x + 7.4 =11.2

Sunny_sXe [5.5K]

The value of x is 3.8

Solution:

Given equation is:

$x + 7.4 = 11.2$

We have to solve the equation for "x"

Move the terms so that you end up with only terms involving x on one side of the sign and all the numbers on the other

Therefore, we get

x + 7.4 = 11.2

When we move 7.4 from left side to right side of equation it becomes -7.4

x = 11.2 - 7.4

Subtract 7.4 from 11.2

x = 3.8

Thus value of x is 3.8
