Answer:
Angle A is 29 degress Angle B is 61 Angle C is 90
Side AB is 5.8 Side BC is 2.8 and Side AC is 5.1
Step-by-step explanation:
Angle A is found using triangle interior theorem.
I found side AC by using law of sines
b/sin b= c/sin c
x/sin 61= 5.8/sin 90( which equal 1)
x=5.1
I found side BC by using pythagoren theorem.
a^2 + b^2=c^2
5.1^2+ b^2=5.8^2
26.01+b^2=36.64
b^2=7.63
b=approx 2.8.
The solution is -0.609611 and -1.64, I do not think you can simply find this by factoring but the only way is graphing it
Answer:
1080°
Step-by-step explanation:
formula to find the sum of interior angles of a polygon is (n-2)×180
octagon has 8 sides so n=8
(8-2)×180
6×180
=1080°
Hello from MrBillDoesMath
Answer: SAS, the second choice
Discussion:
The sides with a single "tick mark" in each triangle have the same length.
The sides with two "tick marks" in each triangle have the same length.
Finally the angle shown in each triangle is the same.
Hence we have congruence by S(ide)-A(ngle)-S(ide) which is the second bullet point from the top of the list.
Thank you,
Mr. B
Answer:
A
Step-by-step explanation:
Round and estimate the sum.
3.41 + 8.051
3 + 8 = 11
3.65 + 7.992
4 + 8 = 12
4.25 + 8.103
4 + 8 = 12
4.89 + 7.431
5 + 7 = 12
The first option is correct.
