Congruent angles are angles that have the same degree or radiant
From C you draw a parallel to AB. From left to right name the angles:
C₁, C₃ and C₂
∠C₁ = ∠A₁ (interior alternate)
∠C₃ = ∠C₃
∠C₂ = ∠B₂ (interior alternate), but ∠C₁ + ∠C₃ + ∠C₂ = 180° (straight line),
Then: ∠A₁ + ∠C₃ + ∠B₂ = 180°
Considering a six-sided spinner, it is found that the probability of spinning a 1 and tossing a head is of .
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem:
- For the spinner, one is one out of six possible outcomes.
- For the coin, a head is one out of two possible outcomes.
Since the events are independent, the probability of spinning a 1 and tossing a head is given by:
.

4.7 -7.25x+ 8.623x -3.8
= (4.7 -3.8)+ (8.623x -7.25x) (combine like terms)
= 0.9+ 1.373x
The final answer is 1.373x+ 0.9~
A:amount of money invested in the account with 3% simple interest
B: amount of money invested in the account with 4.5% simple interest
a+b=25000 ——>a=25000-b
0.03a+0.045b=900
30a+45b=900000
2a+3b=60000
2(25000-b)+3b=60000
50000-2b+3b=60000
B=10000
A=25000-10000=15000
