Find the missing angles

i = 37 f = 50, g = 85, b = 38, e = 76.

Step-by-step explanation:

On the left-most triangle we know that the angle under 273 degrees is 87 because 360 - 273 is 87 and it's a full circle. Now we just do 87 + 56 + x = 180. The last angle, i there is 37. The triangle in the center next. We can find f by subtracting 101 and 29 from 180 which gives us 50. We know that one of the angles is a right angle which is 90 degrees. Now we do 180 - 29 - 90 = x to get 61. To find g let's do 180 because it's a straight line and go for 180 - 61 - 34 = g. g = 85. For the triangle on the top right. We can do 180 - 142 because its a straight line again to find b which is 38. Since its an isos triangle, we know the value of 2 angles now. Angles of a triangle add up to 180. 180 - 2(38) is equal to 104. To find e which is on a straight line, its 180 -104 which is 76.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
