Let x = second angle
let x + 10 = first angle
let 2( (x) + (x+10) ) = third angle.
Since the interior of a triangle equals 180° then,
Inputting the value of x gives us each angle.
second angle = 25°
first angle = x + 10 = 25 + 10 = 35°
third angle = 2( (x) + (x+10) ) = 2( (25) + (25+10) )
= 110°
let x + 10 = first angle
let 2( (x) + (x+10) ) = third angle.
Since the interior of a triangle equals 180° then,
Inputting the value of x gives us each angle.
second angle = 25°
first angle = x + 10 = 25 + 10 = 35°
third angle = 2( (x) + (x+10) ) = 2( (25) + (25+10) )
= 110°
Answer:
see the attached figure.
Step-by-step explanation:
We need to draw a trapezoid with a right angle and an area greater than 40 square inches
See the attached figure
The area of the trapezoid = 0.5 ( base_1 + base_2 ) * height
So, as shown ABCD is a trapezoid with a right angle at A
base_1 = 14 inches , base_2 = 10 inches and the height = 5 inches
So, the area = 0.5 ( 14 + 10 ) * 5 = 0.5 * 24 * 5 = 60 square inches > 40
Note: we can use any numbers other than 5 , 10 , 14
for example: 5 , 8 , 12 in this case the area = 0.5 * (8+12) * 5 = 50 > 40
<u>The point is choose any numbers which gives area > 40</u>
Given
An algebraic expression is the difference between seven times a number and three times that number.
To find:
The algebraic expression.
Solution:
Let x be the unknown number.
Multiplication is used for times and subtraction is used for difference.
7 times of a number = 7x
3 times of that number = 3x
The difference between seven times a number and three times that number is
Therefore, the algebraic expression for the given statement is 7x-3x and its simplified form is 4x.
