Answer:
$42 - 19 = 23 - 15 = $8
Step-by-step explanation:
(a) m∠a = 100°
(b) m∠b = 80°
(c) m∠c = 100°
Solution:
Given 3rd and 4th street are parallel lines and King Ave is a transveral line.
<em>Sum of the adjacent angles in a straight line = 180°</em>
⇒ m∠a + 80° = 180°
⇒ m∠a = 180° – 80°
⇒ m∠a = 100°
∠c and ∠a are vertically opposite angles.
<em>If two lines are intersecting, then the vertically opposite angles are congruent.</em>
⇒ ∠c ≅ ∠a
⇒ m∠c = m∠a
⇒ m∠c = 100°
<em>If two parallel lines are cut by a transversal, then the corresponding angles in the same side of the transversal are congruent.</em>
80° and angle b are corresponding angles.
⇒ m∠b = 80°
Hence m∠a = 100°, m∠b = 80° and m∠c = 100°.
If I'm right, then the answer would be B. 800. Hope I helped!
Answer:
31 in sq
Step-by-step explanation:
The interior shape is inside the exterior shape
first get the area of the big shape
9 times 15 = 135 in sq
now get the area of the interior shape:
8 times 13 = 104 in sq
now subtract interior shape from exterior
135 - 104 = 31 in sq
that's the shaded part
