sukhopar [10]

Answer:

False

Step-by-step explanation:

the area (A) of a rectangle is calculated as

A = length × breadth

= (x + 5)(x - 5) ← expand factors using FOIL

= x² - 5x + 5x - 25

= x² - 25 ≠ x² - x - 15

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.

Number 1:

$87+112+92=291$

$360-291=69$

Number 2:

$124+71+68=263$

$360-263=97$

Number 3:

$95+46+74=215$

$360-215=145$

Number 4:

$72+49+89=210$

$360-210=150$

Number 5:

$69+65+98=232$

$360-232=128$

Number 6:

$77+123+86=286$

$360-286=74$

Hope this helped!
