Answer:
110 Degrees
Step-by-step explanation:
The sum is when different numbers are added.
When all angles are added it adds up to 180 Degrees for any triangle.
Triangles have three sides and two are given as 50 Degrees and 20 Degrees.
There is one angle remaining.
50 Degrees + 20 Degrees = 70 Degrees
Therefore, the last angle must be 110 Degrees. (180-70)
Answer:
Step-by-step explanation:
Lets say Rhonda drove x miles, then Jamie drove 2x miles
x+2x=90
3x=90 divide each side by 3
x=30
so Rhonda drove 30 miles and Jamie drove 30*2=60 miles
Work shown above!
Length would be 8 feet
Width would be 4 ft
Equation would be either:
Area = 2w^2 or
32 = 2w^2 which is the same thing except area was replaced with it's actual number
Answer:
All except 4th and last.
Step-by-step explanation:
The one that says equation is definitely wrong because it doesn't have an equal sign anywhere (there is nothing to solve there).
The one that says 5 plus x^2 that means 5+x^2 instead of 5x^2.
They should have said 5 times x^2 there which actually means 5x^2.
So I don't like the way some of these are written but the only two that are really wrong are the 4th one and the last one.
