Answer:

:)

Step-by-step explanation:

ok so first you have to find the area of the white triangles, so the first one is 2 x 4= 8 cm2 and the second one is 3 x 2.5= 7.5 cm2, 8+7.5= 15.5 cm2, so the non-shaded region is 15.5 cm2, ok now find the area of the whole rectangle and subtract 15.5 from it hope this helped :)

Can someone please help me with these problems I don't know how to do them. Thank you
german

\bold{FOR \: 1st  \: image }

By straight line angles property,

▶60 + 4x +20 =180

▶80 +4x =180

▶4x = 180 -80

▶4x = 100

x = 25

So, Second angle

▶4 ×25 +20

▶100 + 20

▶120

\bold{FOR \: 2nd \: image }

3x + x =116

4x=116

x = 29

other angle = 3 ×29

=87

\bold{FOR \: 3rd \: image }

ANGLE CAB + ANGLE ACB = 90

2x + x + 30 =90

3x + 30 =90

3x = 90 - 30

3x= 60

x=20

So, angle CAB = 2 ×20 = 40
