The angle B will be equal to ∠B=53.13 degrees.
<h3>What is the triangle?</h3>
Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.
It is given that:-
Three sides of the triangle are:- a= 3, b=4 and c =5
The angle B will be calculated by the following formula;-
∠B=53.13 degrees
Hence the angle B will be equal to ∠B=53.13 degrees.

Answer:
The measurement of EF is 1.98 units
Step-by-step explanation:
In Δ DEF
∵ m∠E = 90°
∴ FD is the hypotenuse of the triangle
∵ m∠D = 26°
∵ EF is opposite to angle D
- We can use the sine ratio to find it
∵ sin D = 
⇒ (opposite side / hypotenuse)
∵ FD = 4.5 units
∴ sin(26) = 
- Multiply both sides by 4.5
∴ 4.5 sin(26) = EF
∵ sin 26° ≈ 0.44
∴ 4.5(0.44) = EF
∴ 1.98 = EF
The measurement of EF is 1.98 units

Answer:
Every half a hour she is making 3.25 or 6.5 a hour
0.5=3.25 1=6.5, 1.5=9.75, 2=13, 2.5=16.25, 3=19.5, 3.5=22.75 4=26 5=32.5
Step-by-step explanation:
Just take the 19.50 she earned and divide it by the 3 hours she worked to get 6.5 per hour
