The interior angles of a hexagon are (2x+17)0, (3x - 25)0, (2x+49)0,
EleoNora [17]

Answer:  a) x= 68, b) 108°, c) 72°, d) 255°.

Step-by-step explanation:

Since we have given that

The interior angles of hexagon:

(2x+17), (3x - 25), (2x+49),  (x+40), (4x-17) and (3x - 4).

So, it becomes :

2x+17+3x-25+2x+49+x+40+4x-17+3x-4=1080\\\\15x+60=1080\\\\15x=1080-60\\\\15x=1020\\\\x=68

ii. Find the smallest interior angle of the quadrilateral.

x+40=68+40=108^\circ

iii. Find the largest exterior angle of the quadrilateral.

180-108=72^\circ

iv. Find the largest interior angle of the quadrilateral.

4x-17=4\times 68-17=255^\circ

Hence, a) x= 68, b) 108°, c) 72°, d) 255°.

Find the size of the angle marked a and b on the diagram
Lana71 [14]

Answer:

Step-by-step explanation:

we know that the total angles around the big triangle are 180° so,  we know the right angle is 90° and we are told that one of the angles is 52° so just find the last angle by

180 = 90 + 52 + X

180 - 90 - 52 = X

38 = X

b = 38°

a = 52°

Turn 32/64 into a percent?
alexandr402 [8]


To turn 32/64 into a percent, you have to divide the numerator by the denominator and then multiply the answer by 100.

So, for this question, divide 32 by 64 which is 0.50. Multiply this decimal by 100 and you get 50.

So 50% is the percent for 32/64.

Hope it helps :)
