Question

angle BAC = ??? ....

Solve it plz....​

Answer 1

Step-by-step explanation:

The fours sides of a rhombus are of equal length.

This also means that opposite angles of a rhombus have equal measure.

The interior angles add up to 360 because there are four side. (n-2)(180)=Interior Angle;

where n=number of sides.

So if the opposite angles are equal then if ABC=64, ABD=ABC=64.

You can solve for the other angles as they will be complementary.

So BCD=90-64=26 and because the other two angles are opposites

BCD=BAC=26.

Answer 2

Find angle BAC ,

Solution :-

In ◼️ABCD

→ angle B is 98°

Total sum is 360

According to the question,

∆ ABC → 180 = angle A + angle C + 98°

→ Angle A + angle C = 62°. ...(1)

And in ∆ADC

→angle A + angle C = 180-82

→ Angle A + angle C =98 ....(2)

In ∆ DAB

When solving these we get,

Angle BAC is 26° .
