Answer:
The sum of all exterior angles of BEGC is equal to 360° ⇒ answer F only
Step-by-step explanation:
* Lets revise some facts about the quadrilateral
- Quadrilateral is a polygon of 4 sides
- The sum of measures of the interior angles of any quadrilateral is 360°
- The sum of measures of the exterior angles of any quadrilateral is 360°
* Lets solve the problem
- DEGC is a quadrilateral
∵ m∠BEG = (19x + 3)°
∵ m∠EGC = (m∠GCB + 4x)°
∵ The sum of the measures of its interior angles is 360°
∴ m∠BEG + m∠EGC + m∠GCB + m∠CBE = 360
∴ (19x + 3) + (m∠GCB + 4x) + m∠GCB + m∠CBE = 360 ⇒ add the like terms
∴ (19x + 4x) + (m∠GCB + m∠GCB) + m∠CBE + 3 = 360 ⇒ -3 from both sides
∴ 23x + 2m∠GCB + m∠CBE = 375
∵ The sum of measures of the exterior angles of any quadrilateral is 360°
∴ The statement in answer F is only true

Answer: +24
Step-by-step explanation: To multiply (-8)(-3), remember that a negative times a negative is always a positive. So (-8)(-3) is +24.
Answer:
90 degrees is a right angle.
Step-by-step explanation:

|____
|___|____________
Imagine this is a graph, that little square of the right would represent 90 degrees.
Angles less than 90 are acute angles, angles over 90 but under 180 degrees would be obtuse, and angles that are equal to 180 degrees are straight.
Answer:
7.7 pounds = 3.5 kilograms
Step-by-step explanation:
Given that,
Weight of a gallon of liquid = 7.7 pounds
We need to find weight in kilograms.
We must know the relation between pounds and kilograms and it is as follows :
1 kilogram = 2.20 pounds
or
1 pounds = (1/2.2) kilograms
7.7 pounds = (7.7/2.2) kilograms
= 3.5 kilograms
Hence, 7.7 pounds is equal to 3.5 kilograms.
