Answer:
Answer is m∠4=40
Step-by-step explanation:
According to the image which i have posted below,we first want to take note that m∠6 & m∠7 are vertical angles. Vertical angles are equal to each other, therefore m∠6 is equal to m∠7.
m∠6 = m∠7 (vertical angles)
11x + 8 = 12x – 4
12x - 11x = 8 + 4
x = 12
so
m∠6 = 11x + 8
m∠6 = 11(12) + 8
m∠6 = 132 + 8
m∠6 = 140
m∠4 = 180 - m<6
m∠4 = 180 - 140
m∠4 = 40
Answer is m∠4=40....
Negative 1 times the square root of 61 is -7.81
A. An integer is a whole number without decimals
If this is rounded to the nearest integer, the number is -8
B. Rounded to the nearest tenth is the first decimal place. Therefore the number would be -7.8.
Answer:
6
Step-by-step explanation:
subtract 40 from both sides
divide both sides by 4.5
you're left with v equals 6
Answer:
f(x) = -5x - 14
Step-by-step explanation:
this table represent a straight line : y = mx +c
first find m which is the slope
m = (-24 - -19)/(2-1) = -5
then find c
-19 = -5(1) + c , c = -14
thus f(x) = -5x -14
The area of the polygon is the sum of the area of rectangle + area of triangle = 316 cm². (Option C)
<h3>
Area of Polygon</h3>
The polygon is composed of a triangle and a rectangle.
Area of the polygon = Area of Triangle + Area of Rectangle
Area of Rectangle = length × width
Length = 21 cm
Width = 14 cm
Area of rectangle = 21 × 14 = 294 cm²
Area of Triangle = 1/2(base × height)
Base = 21 - 10 = 11 cm
Height = 18 - 14 = 4 cm
Area = 1/2(11 × 4) = 22 cm²
Therefore:
Area of Polygon = 294 + 22 = 316 cm².
