Answer:
12.25 i think sorry if im wrong
Step-by-step explanation:
A=4 because √a=-2 the you square each side to make it a=4.
Normally if you have the things legnth
and height, you and another thing, then normally the other thing
would be area and you would have 2 given and 1 to solve.
Probably your question is
legnth=?
Height=1.0
decimal part is confusing, I am
guessing that you mean area
area=0.8
so use formula
height times legnth=0.8
1.0 times blank=0.8
divide both sides by 1.0
blank=0.8/1=0.8
blank=0.8
legnth=0.8
Answer:
x = 45
Step-by-step explanation:
What we know:
- This triangle is an isosceles triangle, so two of the angles are equal to x.
- The two bottom are equal to x.
- The top angle is ninety degrees
- All triangles are 180 degrees
Our equation: 180 = 90 + 2x
- subtract 90 from both sides: 90 = 2x
- divide both sides by 2: 45 = x
- x is 45 degrees
