Answer:
58°
Step-by-step explanation:
<h3>Angle sum property of triangle:</h3>
The sum of all angles of a triangle is 180°.
x + 69 + 55 + x + 78 = 180
x + x + 69 + 55 + 78 = 180
Combine like terms,
2x + 202 = 180
Subtract 202 from both sides,
2x = 180 - 202
2x = -22
Divide both sides by 2,
x = -22/2
x = -11
∠A = x + 69
= -11 + 69
Answer:
use a calculator itl be easy
Step-by-step explanation:
substitute x to 150
=0.00125(x)^4+x-3
=0.00125(150)^4+150-3
WE ARE USING PEDMAS HERE SO BE CARE-FULL <u>parenthesis,exponent,multiplication,division,addition,subtraction</u>
<u>=0.00125(506250000)+150-3</u>
<u>=632812.50+150-3</u>
=<u>632962.50-3</u>
=<u>632959.50</u>

Answer:
11 Square Units
Step-by-step explanation:
Let A be the area of the Rectangle
First statement: The area of the rectangle is increased by seven, we have :
A+7
Second Statement: Four less than twice the area of the rectangle
Twice the Area=2A
Four less = 2A-4
Therefore:
2A-4=A+7
Collecting like terms
2A-A =7+4
A=11
The area of the rectangle is 11 Square Units.
