Answer:
c = 24.34
Step-by-step explanation:
Here, we can use the cosine rule
Generally, we have this as:
a^2 = b^2 + c^2 - 2bcCos A
12^2 = 14^2 + c^2 - 2(14)Cos 19
144 = 196 + c^2 - 26.5c
c^2 - 26.5c + 196-144 = 0
c^2 - 26.5c + 52 = 0
We can use the quadratic formula here
and that is;
{-(-26.5) ± √(-26.5)^2 -4(1)(52)}/2
(26.5 + 22.23)/2 or (26.5 - 22.23)/2
24.37 or 2.135
By approximation c = 24.34 will be correct

Step-by-step explanation:
Apply law of sines.
[tex] \frac{23}{ \sin(22) } = \frac{x}{ \sin(25) } [/tex]
[tex] \frac{23}{ \sin(22) } \times \sin(25) = x[/tex]

Answer:
25.9
Step-by-step explanation:
By sine rule:
[tex] \frac{BC}{ \sin 25 \degree} = \frac{23}{ \sin 22 \degree} \\ \\ BC = \frac{23 \sin 25 \degree}{ \sin 22 \degree} \\ \\ BC = \frac{9.72022002}{ \sin 22 \degree} \\ \\BC = 25.947808156 \\ \\ BC \approx \: 25.9[/tex]

Answers
Answer:
46 degrees
Step-by-step explanation:
You should know that measures QRS, which form a horizontal line, measures up to 180 degrees. (Just like a right angle adds to 90 degrees). So, TRS is 42 degrees and URT is 92 degrees, that would make QRU measure 46 degrees because 180 - 92 - 42 = 46 degrees.
Hope that helps you!! Please give me brainliest!! ;)
Answer:
42°
Step-by-step explanation:
A horizontal, or flat line is 180°. This means the total measures of ∠TRS, ∠URT, and ∠QRU, are 180°. We can subtract the given measures from 180 to find the measure of ∠QRU.
∠TRS = 42°
∠URT = 92°
Subtract 42 and 92 from 180.
180 - 42 - 92 = 46
∠QRU = 42°
m∠QRU in circle R is 42°.

Pqr=qps work out the value of qps
Answers
Answer:
89°
Step-by-step explanation:
Total inner degree of PQRS = (4-2)*180° = 360°
PST is a straight line : 180°
angle PSR = 180-128
=52°
angle RQP + angle QPS = 360 - 52 - 130 = 178°
Angle PQR = Angle QPS
Angle QPS = 178/2 = 89°

find x to the nearest tenth
Answers
The value of the base length x of the right angle triangle to the nearest tenth is 18.4.
What is the value of x?From the diagram;
Angle θ = 49°Hypotenuse = 28Base length x = ?We use trigonometric ratio since its right angle triangle.
Cos = Adjacent / Hypotenuse
Cosθ = Base length / Hypotenuse
Cos( 49° ) = x / 28
x = Cos( 49° ) × 28
x = 0.656059 × 28
x = 18.4
Therefore, the value of the base length x of the right angle triangle to the nearest tenth is 18.4.

Find the 3rd term in the expansion of (a+b)^8 in simplest form.
Answers
Answer:
The fifth term is the middle term of nine, with coefficient given by all the ways of choosing 4 items out of 8 , namely the ways of choosing 4 a 's out of 8 binomial factors.
Step-by-step explanation:
The third term of the expansion is 56a⁵b³
How to determine the third term?The expression is given as:
(a + b)^8
The above expression is a binomial expression, and the nth term of the expression is:
(a + b)^n = nCr * a^(n - k) * (b)^k
Where k = 0, 1, 2.....
So,we have:
(a + b)⁸ = ⁸C₃ * a⁸⁻³ * b³
Evaluate the combination expression
(a + b)⁸ = 56a⁵b³
Hence, the third term of the expansion is 56a⁵b³
