Answer:

The measure of the angles:

24° and 66°

Step-by-step explanation:

Complementary angles sum 90°

then:

(3x + 3) + (10x-4) = 90

3x + 10x + 3 - 4 = 90

13x - 1 = 90

13x = 90+1

13x = 91

x = 91/13

x = 7°

then:

angle 1:

3x+3 = 3*7 + 3 = 21+3 = 24°

angle 2

10x - 4 = 10*7 - 4 = 70 - 4 = 66°

Check:

66° + 24° = 90°

Determine the period of the function g(x) = (cos ;)

Romashka [77]

Answer:

6 $\pi$

Step-by-step explanation:

The period of a sinusoidal function in the form a * cos (b (x + h)) + m is $\frac{2\pi }{|b|}$ . Therefore, we can see that "b" in g(x) is 1/3 and 1/3 substituted into $\frac{2\pi }{|b|}$ is 2 $\pi$ /1/3 which is 6 $\pi$ .

Find the value of that makes ADEFAXYZ.

vovikov84 [41]

Answer:

x = 2/3

DF = 10

scale factor of ΔDEF to ΔXYX is 1:3

Step-by-step explanation:

DF corresponds to XZ and DE corresponds to XY so we can set up a proportion:

6x+6/30 = 8/24

simplify 8/24 to be 1/3

6x+6/30 = 1/3

cross-multiply:

3(6x+6) = 30

18x + 18 = 30

18x = 12

x = 12/18 or 2/3
