Answer:
(√3)/2 -1 ≈ -0.133974596
Step-by-step explanation:
2sin²(30°)tan(60°) -3cos²(60°)sec²(30°)
= 2(1/2)²(√3) -3(1/2)²(2/√3)²
= 2(1/4)√3 -3(1/4)(4/3)
= (√3)/2 -1 ≈ -0.133974596
58% would be 29/50 as a fraction.
92% would be 23/25 as a fraction.
54% would be 27/50 as a fraction.
49% would be 49/100 as a fraction.
20% would be 1/5 as a fraction.
hope this helps! :)
(5, 3)
x y
Plug in:
x + y = 8
5 + 3 = 8
8 = 8
Plug in:
17(5) + 17(3) = 8
85 + 51 = 8
136 = 8
Answer - No, (5, 3) is not a solution to this system of equations.
Answer: 99°
explanation: first, we need to find angle T. we know that angle T and angle R are vertical angles, which means they’re the same. therefore, we solve the equation for x by doing angle T = angle R:
3x + 36 = 6x - 9
subtract 36 on both sides
3x = 6x - 45
subtract 6 on both sides
-3x = -45
divide both sides by -3
x= 15
then, plug in the value of x in 3x+36 to get angle T:
3(15) + 36= 81°
we found that angle T is 81°.
now, we need to find the supplementary angle of angle T. supplementary angles add up together to have a sum of 180°. to find the supplementary angle, subtract angle T from 180°:
180 - 81 = 99°
there we have the answer!
14 = x/3 so first multiply to get rid of the 3 so multiply by 3 on both sides and you should get your answer.
