ANSWER FOR BRAINLIEST :)

Answers

Answer 1

64° + 76° + (2x+14)° = 180° (angle sum of triangle)

140° + 2x+14° = 180°

2x=180 ° - 14 ° -140°

2x=26°

x=13°

Answer 2

Answer:

x = 13

Step-by-step explanation:

the sum of the triangle angles always adds up to 180 degrees, otherwise it is not a triangle.

64 + 76 = 140

180 - 140 = 40.

therefore, the last angle must equal 40 degrees.

2 * x + 14 is the equation we need to us to get to 40 degrees.

40 - 14 = 26

26 / 2 = 13

therefore, x equals 13

now, is we want to check our answer to make sure it is correct,

2 * 13 + 14 = 26 + 14

26 + 14 = 40

76 + 64 = 140

180 - 140 = 40

therefore, it works.

good luck my friend!

Find the surface area of the square pyramid. Draw a net to find the area of the base and each face of the pyramid.

Answers

132! Read on for explanation..... So first step is to choose which to solve (either way works) for example let’s start with the base, the base is a square and a square will always have to the same measurements on each side so for the base you find your measurement, which is 6, so you multiply 6 by 6 to get 36, then you move on to the triangles, for the triangles it’s also asking the same thing as the base, but now it’s asking for the height and the base which the height is 8 and the base is 6, so you multiply those two numbers and get 48 BUT you also have to multiply 48 by 1/2 because the formula for a triangle is A = BH1/2 so 48 multiplied by 1/2 is 24 and instead of doing this for each side, you can simply multiply 24 by 4, because there are 4 triangles that make that shape complete, so 24 times 4 is 96, now you have add the sums, 96 plus 36 equals 132. and don’t forget to put 132 square ft.

Answers

Answer:

1) 3%

Step-by-step explanation:

Answer:

1) 1/125

2) 1/15

3) 1/6

Step-by-step explanation:

Total Cards = 6 + 6 + 3 = 15

Orange cards: 3

1) Chance of first card orange:

3/15, there are 3 orange, 15 total

Chance of second card orange:

3/15, since it is returned, there is the same chance, and the third the same

3/15 * 3/15 * 3/15 = 1/5 * 1/5 * 1/5 = 1/125

2) There are 6 total, 2 green, 2 blue, and 2 red.

The chance of getting a red marble first is 2/6, or 1/3, 6 marbles, 2 red.

The chance of getting blue second is 2/5, since picks aren't replaced.

Chance of getting green third is 2/4, or 1/2, since picks aren't replaced

1/3 * 2/5 * 1/2 = 2/30, or 1/15

3) First spinner has 6 total, 2 are A or B, so 2/6 or 1/3.

Second spinner has 4 total, 2 evens, so 2/4 or 1/2

Now multiply 1/3 * 1/2 = 1/6
