Answer:
5
Step-by-step explanation:
b^2= (5)^2 = 25
So.... b=5 or -5
Answer:
P-E-M-D-A-S
Step-by-step explanation:
Ok, so start with what i call "P-E-M-D-A-S"
P: parentheses | Also known as these: ( )
E: exponents | Its a small number by another number, like the 3 on your screen
M: Multiply | Also Known as x or a dot
D: Divide | i forgot how to make it
A: Add | also known as +
S: Subtract | also known as -
now go in order to solve it, it makes it much more easy!
Using Pythagorean theory the square of the hypotenuse minus the square of the base equals the square of the other side (altitude).
So 8*8=64, 4*4=16, 64–16=48 so the altitude of the triangle is the √48.
Answer:
y ≈ 240.3 ft
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relation between an angle and the sides adjacent and opposite is ...
Tan = Opposite/Adjacent
In this triangle, the interior angle at lower right is the same as the one marked at upper left: 31°. y is the side opposite that angle, and 400 ft is the side adjacent. Then the relation is ...
tan(31°) = y/(400 ft)
Multiplying by 400 ft gives ...
y = (400 ft)·tan(31°) ≈ 240.3 ft
_____
The triangle interior angle at lower right and the angle marked 31° are "alternate interior angles" relative to the transversal marked x and the (parallel) horizontal lines in the figure. Alternate interior angles always have the same measure.
In geometry problems like this one, it means the angle of elevation (above the horizontal) is equal to the angle of depression (below the horizontal).
