Answer:
option 2
Step-by-step explanation:
Since the sign is greater than or equal to it will be pointing to the right since it includes -9 it will be a closed circle
Answer:
2.5

2.5
t
Step-by-step explanation:
Since b = c, the angles B and C are congruent.
180 - 45 = 135
135/2 = =67.5
A = 45
B = 67.5
C = 67.5
a = ?
b = 4
c = 4
Since we know two sides and all three angles, we can use the law of sines to find a.
b/sin B = a/sin A
4/(sin 67.5) = a/(sin 45)
a = 4(sin 45)/(sin 67.5)
a^2 = (4(sin 45)/(sin 67.5))^2
a^2 = 9.37
Answer:
75, 105
Step-by-step explanation:
12. 180-105 = 75
13. 105
The hypotenuse of the right triangle measures 3 units.
<h3>
How to find the hypotenuse?</h3>
Here we know that both legs measure:

If we use the Pythagorean theorem, we will see that the hypotenuse H can be written as:

Then we conclude that the hypotenuse of the right triangle measures 9 units.
