Use a calculator to approximate acute angle A to the nearest whole degree sin A=0.6 Measure of angle A =
Bas_tet [7]

Answer:

m \angle A = 37^{\circ}

Step-by-step explanation:

Let be \sin A = 0.6, then we must solve for A by means of the following expression:

A = \sin^{-1} 0.6 (1)

Since it is an inverse trigonometric function, it can be solved only by numerical methods such as application of infinite series such as Taylor series. This approach is used for current scientific calculators. According to scientific calculator we have the following result:

A = \sin^{-1} 0.6 \approx 36.87^{\circ} \to 37^{\circ}

5 (2y - 2) + 4 = 4 what does y equal
tensa zangetsu [6.8K]
Solve your equation step-by-step.

5(2y−2)+4=4

Simplify both sides of the equation.

5(2y−2)+4=4

(5)(2y)+(5)(−2)+4=4(Distribute)

10y+−10+4=4

(10y)+(−10+4)=4(Combine Like Terms)

10y+−6=4

10y−6=4

Add 6 to both sides
.
10y−6+6=4+6

10y=10

Divide both sides by 10.

10y/10 = 10/10

\huge{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{y = 1}}}}}}}}
