Answer:
So we can try all answers with -10 we get -11/4 = -2.75. And that is less so it works. -7 wont work because -8/4 = -2 and its not less than its the same. So the higher you go it wont work. So that rules out -7, -5, and -1. For 0 you get -1/4 = 0.25 which also doesn't work.
<h2><u>
Only 1 answer: A</u></h2>
PART A:
1) plug in values given to you in the area formula: A=b^2--> 788=s^2
2) solve for x: x=28.071
PART B:
1) find he perimeter formula of a square: P=4s s being a side
2) plug in the value you got for part a as s: P=4(28.071) therefore, P=112.285
Answer:
x = 13.5
Step-by-step explanation:
To find x, we use the sine rule
For the sine rule,
the ratio of the sides to the sine of the angle facing the side is equal for all the sides of the triangle
Thus,
x/sin 34 = 11/ sin 27
x = 11 sin 34/sin 27
x = 13.5
10/9 can be simplified to 1 1/9, so it would be closer to 1
Answer:
Using trigonometric ratio:
From the given statement:
and sin < 0
⇒
lies in the 3rd quadrant.
then;
Using trigonometry identities:
Substitute the given values we have;
Since, sin < 0
⇒
now, find 
:
Substitute the given values we have;
Therefore, the exact value of:
(a)
(b)
