If m∠ABC=7x-2 and ∠CDE=5x+16 are congruent, find m∠ABC?
2 answers:
Answer: m∠ABC = 61°
Step-by-step explanation: Since angles are congruent, make the equation
7x-2 = 5x + 16
7x-5x = 16 +2
2x = 19
x = 9
Substitute 9 for x
7(9) -2 = m∠ABC . and 5(9) + 16 = m∠CDE
63-2 = 61° = m∠ABC 45 + 16 = 61 True!

x=-2
Step-by-step explanation:
x= -b/2a
b=4
a=1
x=-4/2*1
x=-4/2
x=-2
Probability of an Ace= 4/52
Probability of a King = 4/52
Probability of an Ace or a King = P(Ace) + P(King)
=4/52 +4/52
=8/52
=2/13

<h2>Volume Of Prism</h2>
Here is the base of a prism if the height of the prism is 5cm what is it’s surface area? what is it’s volume.
<h3>Solution:</h3>
- Volume = s²
- V = 5cm
- V = 5cm x 5cm
- V = 25cm²
- So The Surface area of Prism is 25cm².
