Answer is B
Step-by-step explanation:
You have the side opposite the angle and the Hypotenuse so use soh
Sine(x) = opposite/Hypotenuse
Sine(x) = 9/19
X = sin-1(9/19) - - - - - here the - 1 is to the power of
X= 28,27371363
X= 23,3
What? Sorry can’t understand
The value of x
3x°+46°+(2x-1°)=180°(angle sum of △)
5x+45=180°
5x=180°-45
x=135÷5
x=27
x is 27
put x into angle B,we have
2(27)-1
=53
thus angleB is 53°

Answer:</h3>
- Option A
- Option D
<h3>
Solution:</h3>
- In order to multiply fractions, we should multiply the numerator of the first fraction times the numerator of the second fraction, like so:
- 3•5=15
- Do the same with the denominator:
- 10•7=70
- 15/70 is the answer.
- Same with the other fractions:
- 7•2=14
- 10•4=40
- Hence, 14/40 is the answer.
Hope it helps.
