Answer:
(-111)
Step-by-step explanation:
My best explanation to this question is:
Elena has summed the total of all three angles in the straight angle to get 180°; <DAB, <BAC , and <CAE. But this does not mean a total of three angles will ALWAYS equal 180°. If one angle is greater than the other two, then there is a possible chance the angle will not be 180°. If the angles are scalene, then there is a greater chance the angle may not be 180°.
This may be wrong, so you don’t have to come up with my response exactly, just modify it to what you need. Wish you luck.
Sketch a right triangle, with hypotenuse = 425. Solve for y, the side opposite the 47-degree angle, using the sine function.
Sin 47 = opp / hyp
Sin 47 = y / 425
Y= 425 times (Sin 47)
Y= 425 times (????) [evaluate Sin 47]
Answer:
0.83
Step-by-step explanation:
0.1 + 0.73 = 0.10 + 0.73 = 0.83
