Step-by-step explanation:
sin theta =p/h
sin 42=x/13
0.66×13=x
x=8.69

It is 70° because the other triangle has the same angle and it is labeled 70° in the other triangle.
Answer: 70°
Are we trying to find f? If so,
15f = 45
/15 /15
F = 3
Answer:
(b) tangible approximation of the product that often look and feel like the product
Step-by-step explanation:
"Physical" means it exists as an object in the real world, not just as a model on a computer screen. "Prototype" means it is an approximation of the finished product, lacking in one or more details of appearance, structure, or functionality.
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
