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>

<em></em>

Debora [2.8K]

Answer:

  (b)  0 = Yes; 1-9 = No

Step-by-step explanation:

Among digits, 10% of 10 digits is a single digit. Any answer choice that suggests more than one digit be used for "yes" is not appropriate. A good choice is ...

  0 = Yes; 1-9 = No . . . . . choice (b)
