Answer:
1) x = 8
2) ∠RPS = 36°
Step-by-step explanation:
<u>GIVEN :-</u>
- ∠QPS = 180°
- ∠QPR = 7x + 88
- ∠RPS = 3x + 12
<u>TO FIND :-</u>
- Value of x
- Measure of ∠RPS
<u>FACTS TO KNOW BEFORE SOLVING :-</u>
In a straight line , if there are two angles such that their sum is equal to straight angle (or 180° in other words) , then those angles are known as linear pair.
<u>PROCEDURE :-</u>
1)
Measure of ∠QPS = 180° and it comprises of ∠QPR & ∠RPS.
⇒ ∠QPR & ∠RPS are linear pair.
⇒ ∠QPR + ∠RPS = 180°
⇒ 7x + 88 + 3x + 12 = 180°
⇒ 10x + 100 = 180
⇒ 10x = 180 - 100 = 80
⇒ x = 80/10 = 8
2)
x = 8. So,
∠RPS = 3×8 + 12 = 24 + 12 = 36°

Answer:
25.1 inches
Step-by-step explanation:
Radius of the circle = 4 inches
We have to calculate the value of Circumference of the circle.
The formula to calculate the circumference is:
Circumference = 2πr
We have to use π = 3.14, as said in the question:
So using the values, we get:
Circumference = 2 x 3.14 x 4 = 25.12 inches
Number of decimals in radius is zero, so we have to round the answer to one decimal place as said in the question.
Therefore, the circumference of the circle rounded to one decimal place will be 25.1 inches
Answer:
47.10
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that ...
... Cos = Adjacent/Hypotenuse
The value y is the length of the hypotenuse, and the given length 35 is the side adjacent to the given angle. Thus, the cosine relationship will be helpful.
Filling in the given values, we have ...
... cos(42°) = 35/y
Multiplying by y/cos(42°), we can find y to be ...
... y = 35/cos(42°) ≈ 35/0.7431
... y ≈ 47.10
Y will be approximately 47.10 in length
Step-by-step explanation:
we will use this form that we memorized in our schools ............. SOH CAH TOA
CAH means , Cos ∅= Adjacent/Hypotenuse
Given values
∅ =42°
hypotenuse= y
adjacent side length = 35
now putting in our values into
Cos ∅= Adjacent/Hypotenuse
OR
cos(42°) = 35/y
by multiplying y on both sides we get
y= 35/cos( 42°)
cos(42°)= 0.743
so y= 35/0.743
y = 47.10632
OR
y ≈ 47.10
