Quick it is due in 30 mins plz do quick
dimulka [17.4K]

Answer:

1. 69°

2. 97°

3. 145°

4. 150°

5. 128°

6. 74°

Step-by-step explanation:

To find the angle measure of the missing angle, we have to note that the angle measures of a quadrilateral will all equal up to be 360°.

If we know 3 out of the 4 angles and the sum of the angles, we can add up the angles we know then subtract that from 360.

<em>Number 1:</em>

87+112+92=291

360-291=69

<em>Number 2:</em>

<em></em>124+71+68=263<em></em>

<em></em>360-263=97<em></em>

<em></em>

<em>Number 3:</em>

<em></em>95+46+74=215<em></em>

<em></em>360-215=145<em></em>

<em></em>

<em>Number 4:</em>

<em></em>72+49+89=210

360-210=150

<em>Number 5:</em>

<em></em>69+65+98=232<em></em>

360-232=128

<em>Number 6:</em>

<em></em>77+123+86=286<em></em>

<em></em>360-286=74<em></em>

<em></em>

30 students played soccer

9 students played cricket and soccer

x students played neither cricket nor soccer

3x students played cricket only.

we can see that in the first set 21 appears and in the middle of the set 9 because it says 30 students played soccer adding x and 3x we have the following formula

30 + x + 3x = 50 where x is equal to 5 then ask us Determine the number of students who played cricket. then the value would be 3x + 9 = (3x5) + 9 = 24
