Step-by-step explanation:
Answer:
Part 1) 0.669
Part 2) x=23.78 cm
Step-by-step explanation:
Part 1) we have
cos(48°)
Using a calculator
cos(48°)=0.66913
Round to the nearest thousandth
0.66913=0.669
Part 2) we know that
In the right triangle of the figure
The cosine of angle of 18 degrees is equal to divide the adjacent side to the angle of 18 degrees by the hypotenuse of the right triangle
so
cos(18°)=x/25
x=(25)cos(18°)=23.78 cm
Step-by-step explanation:
b + 81° = 117° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
b = 117° - 81°
b = 36°
for no. 14
The angles that are congruent to < 1 are < 4 and < 8.
