First, lets assign label to the interior angles of the triangle.
Since angle 130° and angle A are on the same straight line, they are supplementary angles; therefore:
130+A=180
A=180-130
A=50

Next, angle B and angle 134° are also on the same straight line, so they are supplementary as well, which means:
B+134=180
B=180-134
B=46

Now, to find angle C remember that the sum of the interior angles of a triangle is 180°; therefore:
A+B+C=180
50+46+C=180
C=180-50-46
C=84

Finally, we also know that angle x and angle C are on the same line, so they are supplementary angles just like before; therefore:
x+C=180
x+84=180
x=180-84
x=96

We can conclude that the measure of our angle x is 96°.

MariettaO [177]

Answer:

2x - 0.4x ;

8x/5 ;

Yes

Step-by-step explanation:

Let number of miles = x

Arlene:

Double number of miles = 2 * x = 2x

Subtract 20% of the result :

2x - 20% of 2x ;

2x - 0.4x

Raul:

Divides Number of miles by 5 ; x / 5

Multiplies result by 8 ;

8 * (x/5) = 8x /5

To know if expressions are equivalent :

Let x = 10 miles

Using Arlene's expression:

2x - 0.4x

x = 10

2(10) - 0.4(10) = 16

Using Raul's expression :

8x / 5

(8*10) / 5

80/5

= 16

Since they give the same result, we can conclude that the expression are equivalent

the height in feet above the ground of an arrow after it is shot can be modeled by y=-16r^2+63r+4.Can the arrow pass over a tree
miss Akunina [59]

Answer:

yes

Step-by-step explanation:

y=-16r^2+63r+4

maximum value of y :

y'=0

-32r +63=0

r= 63/32

y = -16(63/32)²+63(63/32)+4

= -4 + 124 + 4 = 124 ft

124 > 68

the Arrow can pass over the tree
