Answer:

Step-by-step explanation:

(hypotenuse)² = (adjacent)² + (opposite)²

(opposite)² = (hypotenuse)² - (adjacent)²

(adjacent)² = (hypotenuse)² -  (opposite)²

up row

1) x² = 9² + 7² = 81 + 49 = 130

x = 11.4 cm

2) x² =  6² + 4² = 36 + 16 =  52

x = 7.2

3) x² = 4.3² + 7.7² =  18.49 +  59.29 = 77.78

x =  8.8 cm

Down row

1) x² = 7² - 3² = 49 -9 = 40

x = 6.3 cm

2) x² = 6.4² - 2.9² =  40.96 + 8.41 = 49.37

x= 7.02 cm

3) x² = 7.2² - 5.3² = 51.84 - 28.09 = 23.75

x = 4.9 cm

Find the solution to the system of equations-2 + 2y = -4 3x + 3y = -18
AfilCa [17]

Answer:

\boxed{x = -2~~and~~ y = -4}

Step-by-step explanation:

-2x + 2y = -4 (times 3) -6x + 6y = -12

3x + 3y = -18 (times 2) 6x + 6y = -36

.

-6x + 6y = -12

<u>6x + 6y = -36 </u>+

12y = -48

y = \frac{-48}{12}

y = -4

.

Substitute the value of y to the one of equations

-2x + 2(-4) = -4

-2x - 8 = -4

-2x = -4 + 8

-2x = 4

x = \frac{4}{-2}

x = -2

In a right triangle with acute angle of measure theta, sintheta=1 /2. What is the value of costhetatheta? Draw a diagram as part
Stells [14]

Answer:

0.866

Step-by-step explanation:

By definition

sin \theta = \frac{Opposite}{Hypotenuse}

cos \theta = \frac{Adjacent}{Hypotenuse}

We know that sin \theta = 0.5. Inverse of sine is arcsin, so, angle \theta is computed as

\theta=arcsin(0.5)=30

Therefore, cosine of \theta is  

cos (30°) = 0.866

Pls help need it ASAP<br> :)
Elenna [48]

Answer:

x = 4

y = 13

Step-by-step explanation:

x + y = 17

y = 2x + 5

substitute for y:

x + (2x + 5) = 17

reduce:

3x + 5 = 17

subtract 5 from each side:

3x = 12

divide both sides by 3:

x = 4

y = 2(4) + 5

y = 13
