The figure consists of a rectangle and a circle.
first lets find the sides of the triangle
sides of the triangle are 4+4=8 and 3+1=4
therefore area of the rectangle is 8*4=32
now area of semicircle =πr^2/2 = π2^2/2=2π=6.3
we have to add the area of rectangle with the area of semicircle
this is because it the given figure no part of area of circle and rectangle are in common.
therefore total area of given figure = 32+6.3=38.3
Five less than twice what negative number squared is 157 <- put into an expression
-5 + 2(-x^2) = 157
Now simplify:
-5 + -2x^2 = 157
-2x^2 = 162
-2x^2 - 162 = 0
2x^2 + 162 = 0
x^2 + 81 = 0
Depending on what numbers I'm rounding to, hundreds, tens, ones etc
If the ones place is 4 and lower, I would round to 30. If the ones place is 5 and higher, you would round to the next tens place. That would make 89 to 90.
Hope This Helps!
The +5 because that's the y value on the graph
Answer:
Step-by-step explanation:
In a right triangle, the sides forming the right angle also determine the angle opposite one of the sides.
Tan(29) =26/x Multiply both sides by x
x tan(29) = 26 Divide by tan(29)
x = 26/tan(29) Find tan(29)
x = 26/0.5543 Divide
x= 46.9
