Sine = opposite / hypotenuse
cosine = adjacent / hypotenuse
So, in a right triangle which has the opposite side equal to the adjacent side, we will have the sin (theta) = cosine (theta)
This would be an isosceles right triangle which is also called a 45 45 90 triangle. 
sine (45) = 0.70711 and the
cosine (45) = 0.70711

Is the point (-3, 2) a solution of x - 5y < 7? Explain how you know.
aivan3 [116]

Answer:

yes

Step-by-step explanation:

Substitute x = - 3 and y = 2 into the left side of the inequality and compare the value obtained with the right side.

- 3 - 5(2) = - 3 - 10 = - 13 < 7

Thus (- 3, 2) is a solution of the inequality

Perform the indicated operation.<br><br> 4/11 · 10/8<br><br> 4/11<br> 5/11<br> 6/11
Dimas [21]
4/11 * 10/8

Multiplying fractions
1) multiply the numerators: 4 * 10 = 40
2) multiply the denominators: 11 * 8 = 88
3) simplify the fraction
40/88 ⇒ 10/22 ⇒ 5/11

40 ÷ 4 = 10
88 ÷ 4 = 22

10 ÷ 2 = 5
22 ÷ 2 = 11

4/11 * 10/8 = 5/11
