Answer:
m<ACB = 107*
Step-by-step explanation:
First we have to find the angle of m<CEB.
We know that the value of that angle plus m<CEP equals a total of 180, so we subtract the value that we have (147*) from 180 and we get 33*.
33* Is also the value of m<CAB.
33+40 = 43. 180-43 = 107.
Answer:
48 inches
Step-by-step explanation:
There are 12 inches in 1 foot. So multiply by 12 to convert from feet to inches.
4 × 12 = 48
4 feet = 48 inches
A(1.3) (3,1) idk if it’s right but seems like the right answer
Answer:
Zero
Step-by-step explanation:
any absolute value bars come off so -6+6=0
Answer:
Base = 24 cm or 10cm
Step-by-step explanation:
REMEMBER:
An isosceles triangle ABC with base BC = ‘b' & height AD = ‘h' & its equal sides =13 cm & area = 60 cm²
Using the formulas
There are 2 solutions for
≈
Less complex:
Area of a triangle = 1/2 * b * h = 60
=> h = 120/b
In right triangle ABD
13² = h² + b² /4 ( by Pythagoras law)
=>169 = 120²/b² + b²/4
=>676 b² = 57600 + b^4
=> b^4 - 676 b² + 57600 = 0
=> b² = 676 +- √(676² - 4*57600) / 2
=> b²= 676 +- √(226576) /2
=> b² = (676 +- 476 )/2
=> b² = 1152/2 , 200 /2
=> b² = 576 , 100
=> b = 24, 10
So, Base = 24 cm or 10cm
