Answer:

∠A = 32°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tanA = $\frac{opposite}{adjacent}$ = $\frac{5}{8}$ = 0.625, thus

A = $tan^{-1}$ (0.625) = 32°

Evaluate each of the following to three significant figures, and express each answer in SI units using an appropriate prefix: (a

Softa [21]

Answer:

a). $4.86\times 10^{-15}$ m

b). $4.21\times 10^{-2}$ m³

c). $7.00\times 10^{3}$ N²

Step-by-step explanation:

In this question we have to convert each option into SI units.

a). $4.86(10^{-6})^{2}$ mm

= $4.86\times (10^{-12})\times (10^{-3} )$ m

= $4.86\times 10^{-15}$ m

b). (348 mm)³

= $(348)^{3}\times (10^{-3})^{3}$ m³

= $42144192\times 10^{-9}$ m³

= $4.21\times 10^{-2}$ m³

c). $(83700)^{2}\times (10^{-3})^{2}$ N²

= $700569\times 10^{4}\times 10^{-6}$ N²

= $7.00\times 10^{9}\times 10^{-6}N^{2}$

= $7.00\times 10^{3}$ N²

Check the solution.

Julli [10]

Answer:

Both equations, when we replace the solution, generate identities.

Step-by-step explanation:

We are given the following system:

y = x - 7

y = -4x + 3

We are given the following solution.

(2,-5).

First equation:

We have to show that when x = 2, y = -5. So

y = x - 7

-5 = 2 - 7

-5 = -5

So ok

Second equation

We have to show that when x = 2, y = -5. So

y = -4x + 3

-5 = -4(2) + 3

-5 = -8 + 3

-5 = -5

We generate both identities, so the solution is checked.
