what does this mean when a rhombus is split into 2 triangles ; what's the formula to find the value of x? also it's about polygo
1 answer:
Answer/Step-by-step explanation:
The rhombus when split into two triangles will give us two equilateral triangles that are congruent to each other.
Therefore:
The two bases of both triangles will have equal angle measures of 4x + 5 each and a third angle measure of 8x - 6.
✅Formula to find the value of x:
(8x - 6) + 2(4x + 5) = 180° (sum of triangle)
8x - 6 + 8x + 10 = 180
8x + 8x - 6 + 10 = 180
16x + 4 = 180
16x + 4 - 4 = 180 - 4
16x = 176
16x/16 = 176/16
x = 11

the solution is where the line cross on the y axis, which is on 0
so y = 0
Answer: 7
Step-by-step explanation:
Since we are given the information that a group of friends had 28 driveways to shovel and that one of them shoveled 1/4 of the driveways.
The number of driveways that he shovel will be:
= 1/4 × 28
= 7
Therefore, he shovel 7 driveways.
