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°.

The average of 4 numbers is 98. If 3 of the numbers are 86, 87, and 91, what is the 4th number?
astraxan [27]
Average of 4 numbers, if the numbers are x,y,z,t then the average is (x+y+z+t)/4=average so

average=98
if 3 of the numbers are 86, 87 and 91 then what is the fourth number
assign
x=86
y=87
z=unknown
91=t

(86+87+z+91)/4=98
do parenthasees first
(264+z)/4=98
multiply both sides by 4 to get rid of fraciton
264+z=392
subtract 264 from both sides
z=128

the fourth number=128
