-66+42
=-24 since it is negative
Answer:
20 ft²
Step-by-step explanation:
the area (A) of a triangle is calculated using the formula
A =
bh ( b is the base and h the height )
here b = 5 and h = 8
A =
× 5 × 8 = 20 ft²
Answer:
80
Step-by-step explanation:
in the figure above, angle 100 degrees is corresponding to the angle co - interior to angle x
that is
if we put an angle that is at the upper left of x, we can call that y which is corresponding to 100 degrees
since y is corresponding to 100 degrees, it automatically becomes the same as 100 degrees
therefore y=100
now, from the first line above, we know that x and y are co-interior which means that they both add up to 180 degrees
that is
x+y=180
we know that y = 100
therefore,
x+100=180
collect like terms and
x = 180-100
therefore,
x= 80
thank you!!
