Answer:
area = 32 in²
Step-by-step explanation:
the area (A) of a triangle is
A = 
bh ( b is the base and h the perpendicular height )
here b = 8 and h = 8, hence
A = × 8 × 8 = 32 in²
Answer:
2.5
Step-by-step explanation:
5(0.5)=5×5/10
=25/10
=2.5
Answer:
y=-x+4
Step-by-step explanation:
Slope= Difference in y over difference in x position:
(2-8)/(2--4) --> -6/6 --> <u>-1</u>
The slope is -1
We can put what we have so far in slope intercept form: y=-1x+b
The y-intercept (also known as b) in this equation is 4
In slope-intercept form this line would be written as y=-1x+4,
or simply just y=-x+4
Answer: - radical 7 / 4
Step-by-step explanation:
draw a triangle in quadrant III
plug in correct terms
use Pythagorean theorem
to simplify down to find the opposite angle
b= rad 7
