Question

please give me answer . Question number 5 7 8 and 9​

Answer 1

No. 5 angle ABD = 20 , angle ACB = 60

No. 7 50 + 50 = 100 because sum of two interior angle is equal to one exterior angle .

Que.8 and 9 are too long . So I can't .

Answer 2

Answer:

5)a) angle ABD

it is given here angle ADB=70°

angle ABD=(<BAD+70)-180

in the fiqure given <BAC=90°

we know that <DAB and <BAC is a linear pair

linear pair total angle =180

there fore <BAD=45°

so, <ABD=(45+70)-180=75

b)<ACB

there given <BAC=90°

< ACB=(<CBA+90)-180

90/2=45

so <ACB =45

<CBA=45

there for that 2 angles are equal

8) we know that any polygons outer angles sum will be 360°

9)we want to find p

we know there is alinear pair

<y and p

<p =y-180
