1 answer:
Tomtit [17]3 years ago
5 0

Answer:

x = 24 inches

Step-by-step explanation:

We can use similar triangles and proportions to solve.  Put the side of the small triangle over the side of the large triangle

5               8

---------- = -----------------

15                  x

Using cross products

5x = 15*8

5x = 120

Divide each side by 5

5x/5 = 120/5

x = 24

On a number line, point D is at -3, and point E is at 6. The point F lies on DE. The ratio of DF to FE is 2:3. Where does point
expeople1 [14]

Answer: point F is at <u>   0.6   </u> on the number line

=============================================================

Explanation:

The ratio 2:3 scales up to 2x:3x for some positive real number x.

This means the distance from D to F is 2x units, and the distance from F to E is 3x units. Combine those two smaller distances to get 2x+3x = 5x to represent the full distance from D to E.

D is at -3 and E is at 6. This is a distance of 9 units since |-3-6| = |-9| = 9

Set this equal to the 5x from earlier and solve

5x = 9

x = 9/5

x = 1.8

This leads to 2x = 2*1.8 = 3.6

Therefore, we'll move 3.6 units from -3 to -3+3.6 = 0.6 which is the location of point F on the number line.

Notice that from 0.6 to 6 is 5.4 units and that 3x = 3*1.8 = 5.4 matches up to help confirm the answer.

Which statement is false?
Sidana [21]

Trigonometric functions which are related by having the same value at complementary angles are called cofunctions. Cofunctions of complementary angles are equal.

A. csc 20' = csc(90-70)=sec 70

B. cos 87' =  cos (90-3)=sin 3'

C. csc 40' =  csc(90-50) =sec50'  


D. tan 15' = tan(90-75)= cot 75'

Among all the option  c is not correct.

Option C is false.
