What is the value of x?

Mathematics
1 answer:
garik1379 [7]3 years ago
5 0

Answer:

<h2>x = 30°</h2>

Step-by-step explanation:

The angle 30° and 2x are complementary angles.

Two angles are called complementary angles, if their sum is one right angle (90°).

Therefore we have the equation:

30 + 2x = 90          <em>subtract 30 from both sides</em>

2x = 60      <em>divide both sides by 2</em>

x = 30

What decimal is equivalent to 4/5 + 0.05
UNO [17]
To answer this we will add, but before we add we will change 4/5 in to a decimal. to change ANY fraction into a decimal we have to divide the numerator by the denominator. lets do it:- 

4/5 
4 ÷ 5 = 0.8

Now lets substitute 0.8 for 4/5 and then add.

4/5 + 0.05
0.8 + 0.05 = 0.85

CHECK OUR WORK:-

0.85 - 0.8 = 0.05
We were RIGHT!!

So, the decimal 0.85 is equivalent to 4/5 + 0.05.

Hope I helped ya!! xD
