1. Let x represent the missing angle.

The sum of angles in a triangle is 180°

65° + 57° +x =180

122° +x=180°

x=180-122

x=68°

2. Let y represent the missing angle.

Then

y+90°+40°=180°

y+130°=180°

y=180°-130°

y=50°

3. Let the missing angle be t, then

t+20°+130°=180°

t+150° =180°

t=180°-150°

t=30°

4. Let the missing angle be m, then

m+85°+50°=180°

m=180°-50°-85°

m=180-135°

m=45°

5. Let the missing angle be e, then by the exterior remote angle theorem:

137°=102° +e

137-102=e

e=35°

6. Let the unknown angle p, be the missing angle.

Then by vertical angle property and exterior angle property:

p=35° +100°

p=135°

7. Let g be the missing angle, then

g+20°+30°=180°

g+50°=180°

g=180°-50°

g=130°

8)

Let v be the missing angle:

By angle on straight line, and exterior angle theorem property,

g=(180-155)+60°

g=25°+60°

g=85°

Bytecoin is a new cryptocurrency that is currently valued at $243 per coin. You want to make an investment and purchase 1 Byteco
Digiron [165]

Answer:

Step-by-step explanation:

The growth rate of the coin is exponential. We would apply the formula for exponential growth which is expressed as

y = ab^x

y = b(1 + r)^ t

Where

y represents the value of the coin after x months.

x represents the number of months.

a represents the initial value of the coin.

b represents rate of growth.

From the information given,

a = 243

b = 1 + 15/100 = 1 + 0.15 = 1.15

Therefore, the exponential expression to determine the number of months, x it will take for the coin to attain a certain value, y is expressed as

y = 243(1.15)^x

If y = 1000, it means that

1000 = 243(1.15)^x

1000/243 = 1.15^x

4.115 = 1.15^x

Taking log of both sides, it becomes

log 4.115 = xlog1.15

0.614 = 0.061x

x = 0.614/0.061

x = 10 months

It will take 10 months

A. x <= -12

<u>Explanation:</u>

-3x >= 36

-x >= 36/ 3

-x > = 12

x < = -12

When the negative sign is shifted then the greater than equal to sign reverses to less than equal to.

Therefore, x <= -12
