Answer: 64

a = -3, b = 4, c = -5
Sum a+b+c= -3 + 4 -5 = -4
Product abc = (-3)(4)(-5) = 60

If you knew that two angles were complementary and were given the measure of one of those angles, would you be able to find the
vladimir1956 [14]

If we knew that two angles were complementary and were given the measure of one of those angles, then we can find the measure of the other angle by subtracting the given measure of one angle from 90

<em><u>Solution:</u></em>

Given that,

If you knew that two angles were complementary and were given the measure of one of those angles, would you be able to find the measure of the other angle

Yes we can find the measure of another angle

<em><u>Complementary angles:</u></em>

Complementary angles are two angles whose sum is 90 degrees

Therefore, if measure of one angle is given, then we can find the measure of another angle

Measure of another angle = 90 - measure of one angle

<em><u>Example:</u></em>

If x and y are complementary angles

Given that measure of angle x is 45 degrees

Then we can say,

According to complementary angles definition

x + y = 90

45 + y = 90

y = 90 - 45

y = 45

Thus measure of other angle y is found to be 45 degrees

How would I solve this problem if n=5 with no decimals?
Ostrovityanka [42]
This equals to 2/(1/5)+(1/5)/2.
                     =2 x 5+1/5 x 1/2
                     =10+1/10
                     =10 1/10 <---- This is mixed fraction, since you didn't want decimals.

Write the following in terms of sin θ and cos θ; then simplify if possible. (Leave your answer in terms of sin θ and/or cos θ.)
erma4kov [3.2K]

Answer: 1/cos θ

Step-by-step explanation:

From basic trigonometry, csc θ is the short form of cosec θ which is further expressed as

csc θ = 1/sin θ

Also,

tan θ = sin θ/cos θ

Knowing this basis of trigonometry makes the simplification easy for us.

Firstly, expressing the equation in terms of sin θ and cos θ,

The equation becomes csc θ * tan θ = [1/sin θ] * [sin θ/ cos θ]

Further simplifying by multiplication, our answer becomes

1/cos θ
