Find the measures of the interior angles to the nearest tenth. ( Drawing is not to scale)
Answers
Answer:
6). Option (B)
7). Option (C)
Step-by-step explanation:
6) Property of a triangle :
"Sum of all interior angles is 180°"
(x + 2)° + (2x + 2)° + (2x - 1)° = 180°
5x + 3 = 180°
5x = 177°
x =
(x + 2)° = 37.4°
(2x - 1)° = 69.8°
(2x + 2)° = 72.8°
Option (B) is the answer.
7). (4x + 2)° + (2x + 1)° + (x - 1)° = 180°
7x + 2 = 180°
7x = 178°
x =
(4x + 2)° = 103.7
(2x + 1)° = 51.9°
(x - 1)° = 24.4°
Option (C) will be the answer.

What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Cos - 1 0.45 = 63.3°
Cos - 1 0.89 = 27.1°
The angle for which t is a reference is 296.7°.
The angle for which w is a reference is 332.9°.
Therefore the statement which describes the best relationship will be W > t.

Step-by-step explanation:
To find the x-intercept of the line 4x+11y=20, we need to set y=0 and solve for x. This is because the x-intercept is the point where the line crosses the x-axis, which is the point where y=0.
First, substitute y=0 into the equation: 4x+11(0)=20
Simplify: 4x=20
Solve for x: x=5
Therefore, the x-intercept of the line 4x+11y=20 is 5.
