Answer:

Step-by-step explanation:

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.

To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360°.

Therefore:

105° + 360° = 465°

105° - 360° = -255°

18. The area of a right triangle is 30 cm². The length

Olenka [21]

Answer:

Step-by-step explanation:

The area of a triangle is calculated with the following formula:

$\frac{1}{2} *b*h$ (b: base, h: height (or legs))

We can use this formula to find the length of the other leg:

30 = $\frac{1}{2} *b*h$ multiply both sides with 2 to get rid of fraction

60 = b*h one of the leg's length is given as 5 so

60 = 5*h divide both sides by 5

12 = h is the length of the missing leg.

The given expression $8(4)^2+2^4$ is equal to 144 or $12^2$

Solution:

Given expression is:

$8(4)^2+2^4$

We have to evaluate the above given expression

We know that,

$(4)^2 = 4 \times 4 = 16$

$2^4 = 2 \times 2 \times 2 \times 2=16$

Substituting these in above given expression, we get

$8(4)^2+2^4=8 \times 16+16\\\\8(4)^2+2^4= 128+16\\\\8(4)^2+2^4=144$

Also we know that,

$12 \times 12 = 144$

Therefore,

$8(4)^2+2^4=144 = 12 \times 12 = 12^2$

Thus the given expression $8(4)^2+2^4$ is equal to 144 or $12^2$

Solve the system x+3y=1 ; -5x+4y=-5

Dmitry_Shevchenko [17]

Answer:

x=1

y=0

Step-by-step explanation:

x+3y = 1 equation 1

-5x+4y = -5 equation 2

using equation 1 we have:

x+3y = 1

x= 1-3y equation 3

using equation 3 in equation 2 we have:

-5(1-3y) +4y = -5

-5 + 15y +4y = -5

19y -5 = -5

19y = -5 +5

19y = 0

y=0

so we have:

x= 1-3y

x= 1- 3(0)

x=1
