Answer:
sinT = 
Step-by-step explanation:
We require to calculate RT before obtaining sinT
Using Pythagoras' identity in the right triangle
RT² = 30² + 16² = 900 + 256 = 1156 ( take the square root of both sides )
RT = 
= 34 , then
sinT = 
= 
= 
=
Answer:
Step-by-step explanation:
<h3><u>Given data:</u></h3>
Height = h = 1 cm
Base = b = √5 cm
<h3><u>Required:</u></h3>
Area = A = ?
<h3><u>Formula:</u></h3>
<h3><u>Solution:</u></h3>
![\displaystyle Area = \frac{1}{2} (\sqrt{5} )(1)\\\\Area = \frac{\sqrt{5} }{2} \\\\Area = 1.12 \ cm^2\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%28%5Csqrt%7B5%7D%20%29%281%29%5C%5C%5C%5CArea%20%3D%20%5Cfrac%7B%5Csqrt%7B5%7D%20%7D%7B2%7D%20%5C%5C%5C%5CArea%20%3D%201.12%20%5C%20cm%5E2%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
The answer is -220
What you do is take -7 and multiply that by (1+2+3+4+5+6+7+8+9+10+11) and then after that add 11 again and multiply it by 22. It would look like this.
-7 x (1+2+3+4+5+6+7+8+9+10+11) +11 x 22
Simplify that to -7 x 66 +11 x 22
now multiply -7 and 66 to get -462
-462 +11 x 22
multiply 11 and 22
-462 + 242
and your final answer will be -220
Distributive property: 10x - 5 = 6
Add 5
10x = 11
Divide both sides by 10
x = 1.1
