Answer:
145°
Step-by-step explanation:
There are a couple of ways you can get there:
1. ∠ACB is a right angle, 90°. Hence, ∠BAC is the complement of ∠ABC, so is ...
... ∠BAC = 90° -∠ABC = 90° -55° = 35°
Then, ∠BAC and ∠BAD are a linear pair, so total 180°. That makes ∠BAD the supplement of ∠BAC, so ...
... ∠BAD = 180° -35° = 145°
2. ∠BAD is the exterior angle at A for the triangle ABC. It will have a measure that is the sum of the opposite interior angles: given ∠ABC = 55° and right angle ACB = 90°.
... ∠BAD = 55° +90° = 145°
Answer:
2
Step-by-step explanation:
The answer is z result of flipping. Two coins
<span>Total pocket money: N600
Spent as follows:
Books N50
Pen N80
Maths set N270
Bag N150
Food N50
To find: Angles that pen and food represent on pie chart.
Solution: Pie is made on circle, and sum of angles of a circle is 360°.
Angle that pen represent = (80/600)*360° = 48°
Angle that food represent = (50/600)*360° = 30°</span>
