Answer:
Step-by-step explanation:
3x - 5(-5x + 32) = 22
3x + 25x - 160 = 22
28x = 22 + 160
28x = 182
x = 6.5
(1/4 hour)/(1/12 lawn) = 3 hour/lawn
Selection D is appropriate.
Can you provide a picture of the two figures .?
Answer:
(4,3), (−4,8), (−4,3)
(2.5,−4), (0,0), (0,−4)
Step-by-step explanation:
On plotting on graph all form right angled triangle.
Dimension of all triangles and tanФ
- Base=2 Height=5 tanФ 2.5
- Base=5 Height=3 tanФ 1.6
- Base=8 Height=5 tanФ 1.6
- Base =2.5 Height=4 tanФ 1.6
[Here base and height can be interchanged if needed]
Ratio of perpendicular and base of last two triangle is equal.
First two are not congruent to any of other triangle but 3rd and 4th triangle are congruent .
Their coordinates are:
(4,3), (−4,8), (−4,3)
(2.5,−4), (0,0), (0,−4)
