Answer:
3
Step-by-step explanation:
Pythagorean Theorem: a²+b²=c²
You can fill in the numbers you know: a²+4²=5²
(Hypotenuse must be side c)
Square those numbers and you have: a²+16=25
Subtract 16 from both sides: a²=9
Square root both sides and you get: a=3
answer: positive
for example: -2 x -2 x -2 x-2
=4 x -2 x -2
=-8 x -2
=positive 16
You have to show finding the square root of it ______ ___ __
√144x^2 + √225 = √0
which will give you 12x+15=0
12x=15
x=5/4
Answer:
Step-by-step explanation:
take angle B as reference angle
using cosec rule
cosec B=hypotenuse/opposite
cosec B=13/12
cosec B=1.08
B=cosec 67
B=67 degree
for ratio,
cosec B=13/12
