1 answer:
vichka [17]3 years ago
5 0

Answer:

0 can't be squared, so yes. If a decimal stretches on, it's the same value as the number that has the same digits but doesn't stretch on. The only difference is that the one that does is further from 0.

What is the missing side length in this right triangle?
Harrizon [31]

Answer:

A. 15

Step-by-step explanation:

Ooh, look! This triangle is a Pythagorean triple! Without even needing to use a formula, I can tell that you are correct and the answer is A. 15.

It's based off of a 3-4-5 right triangle, because 9-12-15 simplifies to that if you divide every term by 3. It's basically just a bigger version of a 3-4-5 triangle! Isn't math cool:)

Find the value of x please help I give brainly<br> 20 points
fiasKO [112]

Answer:

x=148

Step-by-step explanation:

First, find the missing angle by subtracting 100+48 from 180 (all of the angles in a triangle add up to 180). Then, subtract that from 180 (the angles are a linear pair, so they are supplementry, so they add up to 180) x+32=180.

x=148.
