I can´t see...
Step-by-step explanation:
Answer:
x = 25
<B = 120 degrees
<C = 30 degrees
Step-by-step explanation:
Total angle measure of a triangle - 180 degrees
Add all the angles together to find the value of x
30 + 4x + 20 + x + 5 = 180
55 + 5x = 180
55 - 55 + 5x = 180 - 55
5x = 125
x = 25
<B = 4(25) + 20
<B = 100 + 20
<B = 120
<C = 25 + 5
<C = 30
Answer:
52.4
Step-by-step explanation:
40 hundredths as a decimal is 40/100 which is .40.
The "fifty two" is a whole number which is in front of the ".40" which makes 52.4 or 52.40.
Answer:

; 
Step-by-step explanation:
Given
Required
Arrange the angles from smallest to largest
First, we need to determine the value of x.
Since, it is a triangle:
Substitute values for A, B and C
Collect Like Terms
Solve for x
Solve for A, B and C
From Smallest to Largest, we have:

The values of the trigonometric ratio is 1/4 , √15 / 4 , 4 .
<h3>What are Trigonometric Ratios ?</h3>
When a Triangle is a right angled Triangle then the ratios used to determine the sides and the angles of the triangle are called Trigonometric Ratio.
It is given that in triangle EFG , right angled at F ,
EG = 8 , FG = 2
By Pythagoras theorem
The length of EF is
8² = 2² + EF²
EF = √(64-4) = √60 = 2√15
The value of the trigonometric ratios is
sin E = Perpendicular / Hypotenuse
sin E = 2 / 8 = 1/4
sin G = 2√15 / 8 = √15 / 4
sec G = 1 / cos G = Hypotenuse / Base = 8 / 2 = 4
Therefore the values of the trigonometric ratio is 1/4 , √15 / 4 , 4 .
