Answer:
50
Step-by-step explanation:
(14*14)+(48*48)=c2
196+2304=2500
squared root of 2500=50
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Answer:
they got -21 when they were supposted to get +21
and they also got +6x when they were supposted to get -6x
Step-by-step explanation:
that's because -3 and 2x are multiplied together and when you are multiplying negative and positive number you need to get negative result.
when you are multiplying negative with negative number, you will get positive number.
The simplified algebraic expression for the model is x = -1
<h3>What are algebraic expressions?</h3>
Algebraic expressions are known as mathematical statements gotten when operations such as addition, subtraction, multiplication, division, etc. are operated or used on variables and constants
From the figure given;
We have:
Now, let's add the variables
= x + x - x
= 2x - x
= x
For the constants
= -1^6 = -1
= 1 ^5 = 1
= 1 × -1 = -1
Thus, the simplified algebraic expression for the model is x = -1
