Answer: x=8/81

Step-by-step explanation

3x divide by 3

8/27 divide by 3

it becomes x=8/27 divide by 3 and 3 becomes 1/3

8/27 x 1/3=8/81

x=8/81

Hey mate!
You stuck?

^3 The cube root of 125=5
^2 The square root of 35=5.91
^3 The cube root of 64=4
^2 The square root of 38=6.16

Therefore your answer would be x2= 38, because 6.16 is greater than the other sums.

Hope this helps! :) (Don't forget Brainliest) :)

Please help! i cant solve it

3241004551 [841]

a ≈ 5.2, B ≈ 50°, C ≈ 95°

Solution:

Given data:

A = 35°, b = 7, c = 9

Using cosine law,

$a^{2}=b^{2}+c^{2}-2 b c \cos A$

$a^{2}=7^{2}+9^{2}-2 (7)(9) \cos 35^\circ$

$a^{2}=49+81-126 (0.82)$

$a^{2}=26.68$

Taking square root on both sides.

a ≈ 5.2

Using sine law,

$$\frac{\sin A}{a} =\frac{\sin B}{b}$

$$\frac{\sin 35^\circ}{5.2} =\frac{\sin B}{7}$

Multiply by 7 on both sides.

$$\frac{0.5735}{5.2}\times 7 =\sin B$

Switch the sides.

Sin B = 0.772

$B=\sin^{-1}0.772$

B ≈ 50°

Sum of all the angles of a triangle = 180°

A + B + C = 180°

35° + 50° + C = 180°

85° + C = 180°

C = 180° - 85°

C = 95°

Hence a ≈ 5.2, B ≈ 50°, C ≈ 95°.

Can some one please help on number 8

X=13 1/3

So first you have to add 16 +4 = 20. Then, simplify 3/2 to 1.5. Finally divide 20 by 1.5 = 13.333333333, or 13 1/3
