74+x+85+33= 180 (bc the sum of the angles of a triangle is 180º)
192=180-x
192-180=-x
12=-x
-12=x
<h2>
Answer:
</h2>
Step-by-step explanation:
If a point 
gets reflected about origin,the new point formed after reflection is 
.
Given that 
,
So,
Given that 
,
So,
3 seconds
solve for when y is zero
0 = -16t^2 + 32t + 48
0 = -16(x^2-2x-3)
0 = -16(x-3)(x+2)
x = 3 or -2
-2 is extraneous because time is not negative in this instance so 3 seconds.
- - He runs 1.5 meters each second.
- Solve:
Divide 30/20
<span>=1.5
</span>To answer this we will divide the amount of meters by the amount of seconds. Then your answer will be the amount of meters Earl runs per second. Then we will check our work. Lets do it:-
30 ÷ 20 = 1.5
1.5 meter per second.
CHECK OUR WOK:-
1.5 × 20 = 30
<span>We were </span><span>RIGHT!!
</span><span>So, </span><span>1.5 meters per sec.</span>
