Answer:
x=25
Step-by-step explanation:
180-60=120
35+120+x=180
x=25
Answer:
81+90
Step-by-step explanation:
9^2 + 2[(5+2)^2 -4]
PEMDAS says parentheses first , working inside out
9^2 + 2[(7)^2 -4]
PEMDAS says parentheses first, doe the exponents inside the parentheses
9^2 + 2[49 -4]
Then the subtraction inside the parentheses
9^2 + 2[45]
Then Exponents
81 +2[45]
Then Multiplication
81+90
Finally add
We have 3 children, with each one possibly being a boy or a girl. And so for each child, the probability of being a boy is 1/2 same with a girl so
1/2^3 = 1/8
so it's 1/8 chance of it being a boy.
The length of the hypotenuse is 5.426 meter
Let the two shorter sides of the right angles triangle be denoted as x meters.
The formula for the area of right triangle is given as,
A = ab/2
Where, a and b are the length of the shorter sides of the triangle
Also we have been given the area of the triangle which is 7.36 sq. meter
Thus , A = 7.36
x^2/2 = 7.36
x^2 = 14.72
x = 3.84
Now according to the Pythagoras theorem,
H = √P^2 + B^2
Where, H = hypotenuse
P = perpendicular
B = base
Now putting the required values we get
H = √x^2 + x^2
= √2x^2
= x√2
= 5.426 meter
Hence the length of the hypotenuse is 5.426 meter
