Answer:
520 because 65 x 8 is 520
Step-by-step explanation:
The first one is the correct answer due to 4 is the initial height of the plaint and 0.75 are inches that being added every week
Answer:
cos theta=8/17
8/17=A/H
finding O,
O ² + A² =H ²
(8)²+O²=(17)²
64+O²=289
O²=289-64
O²=225
O=√225
O=15
we know that H=17, A=8, O=15
therefore, the other trigonometric ratios are
sinФ=O/H=15/17
tanФ=O/A=15/8
cosecФ=H/O=17/15
secФ=H/A=17/8
cotФ=A/O=8/15
hope it helps u!
X+y/2=1
-2+6/2=1
-2 + 3 =1 true
⇒ ( -2, 6) is the solution
