Let x=height. then base is x+4. plug what we know into the formula for the area of a triangle
A=½bh
16=½*(x+4)*(x)
32=x²+4x
x²+4x-32=0
(x+8)(x-4)=0
so x can be-8 our 4. when we plug-8 in for x we get a negative height. since a triangle cannot have a negative side length we discard-8 and try 4. height=4 and base=8
Answer:
159 bagels left
Step-by-step explanation:
add the 32 and 37 then subtract the answer from 32 and 37 from 228 and your answer is 159
Answer:
<h2>
43°</h2>
Step-by-step explanation:
The sum of measures of angles in triangle is 180°, so the measure of the ohter acute angle:
180° - 90° - 47° = 43°
An expression is just a mathematical phrase. A numericalexpression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables!
Hope this helped :)
C)90 because if it go all the way around it would be 180 and I don't see that
