Please I need help with this ASAP..Thanks

Answer 1

Answer:

Qu.3 a = 70 degree.

Qu 4. a = 6  b= 4 c = 15  d =9

Step-by-step explanation:

Rules of parallelogram show that diagonal adjacent angles are equal

Then 110 = 110 and 110+110 = 220

Then as angles equal 360 degree we subtract.

a * 2 = 360-220 = 140 degree

Where there are two angles we divide by 2 to find one of them = a as both measures equal double;

a = 140/2 = 70 degree.

Qu 4. a = 6  b= 4 c = 15  d =9

without calculator we simplify

a= 3/4 x 8 = 1 x 8 - 1/4 = 6     = 3/4 +1/4 = 1  then 1 *8 = 8 then 8 -1/4 = 6 or go decimal 0.75 * 8 = 0.40 + 5.60 + total = 6

b = 2/6 x 12 = 1/6 x 12 (2) = 2 (2) = 4       = 1/6 *2 is the same as 2/6 we then *12

c =  3/2 x 10 = 1/2 x 10 (3) = 5 (3) = 15    = 1/2 *3 is the same as 3/2 we then *10

d =  3/12 x 36 = 1/4 x 36 = 9  = decimal 0.25 x 36 = 1.50  |  + 7.5 = 9
