Please help me, i will make brainliest if correct

x = 7

Step-by-step explanation:

the front triangle is isosceles because it has two sides that are equal which means the angles that created those sides are also equal

so the bottom right angle is also 70 degrees

if two angles are 70 degrees, that adds to 140 degrees

since a triangle has 180 degrees then one portion of the right angle must be 40 degrees and the adjacent angle (∡2) must be 50 degrees

∡2 is 8x - 6 so create this equation:  50 = 8x - 6

8x = 56

x = 7

the answers c

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
