Question

In the figure two circles intersect at D. angle BCD = 80 degree, Angle EFG = 70 degree. what is the measure of angle BAD? what is the measure of angle EDG? what is the measure of angle ADC? what is the measure of angle ABC?​

Answer 1

Answer:

Given: In ΔABC, ∠A = 60° and ∠B = 70°

Using angle sum property:

∠A + ∠B + ∠C = 180°

⇒ 60° + 70° + ∠C = 180°

⇒ 130° + ∠C = 180°

⇒ ∠C = 180° − 130°

= 50°

We know that angle in a semi circle is a right angle.

Answer 2

Answer:

What differentiates a homogeneous mixture from a heterogeneous mixture?

(a)Mixture 2 is homogeneous because the components of a homogenous mixture

always form separate layers.

(b)Mixture 1 is homogeneous because the composition is uniform throughout the

mixture.

(c)Mixture 2 is heterogeneous because the components of a heterogeneous mixtures

are always liquid.

(d)Mixture 1 is heterogeneous because the components of the mixture are not visible

from the naked eye.
