The diagram shows a right-angled triangle.
earnstyle [38]

Answer:

x ≈ 31.0°

Step-by-step explanation:

From the right triangle given in the picture,

By applying tangent rule,

tan(x) = \frac{\text{Opposite side}}{\text{Adjacent side}}

tan(x) = \frac{9}{15}

x = \text{tan}^{-1}(\frac{9}{15} )

x = \text{tan}^{-1}(0.6)

x = 30.96

x ≈ 31.0°

Therefore, measure of angle x is 30.0°

What are two consecutive integers that have a sum of -67
valkas [14]

Answer:

The two integers are -34,-33

Step-by-step explanation:

x 1st integer

x+1 2nd integer

The sum is -67

x+x+1 = -67

Combine like terms

2x+1 = -67

Subtract 1 from each side

2x+1-1 = -67-1

2x= -68

Divide by 2

2x/2 = -68/2

x = -34

x+1 = -34+1 = -33

Pls help me with 13 you will get Brainly the instructions are to evaluate the following a=6, b=3,c=2 please answer this question
scoundrel [369]

You have to plug in the values into the equation.

Since a=6, all the a's in the equation would be replaced by 6 and same goes for the b.

^ means exponent btw

= -[2(6)^2 -6- (5(6)^2-3(3)) -4(6)^2 +2(3)]

Calculate/ simplify

= -[2(36)-6 - (5(36) -9)-4(36)+6]

Multiply all the things in parenthesis

= -[72-6-(171)-144+6]

Add/subtract

= -[-243]

Negative times negative becomes positive therefore, the answer becomes 243

Can you help this is my little sisters work
Olin [163]

Answer:

There are 15 ounces left in the bucket.

Step-by-step explanation:

Starting with 30 ounces.

If Amy used 1/10 and Carl used 2/5 (4/10), we add that to get 5/10, or 1/2.

Half of 30 is 15, so there's your answer!

Hope this helped. :)
