Answer:
Do the same thing for the other exercises and you should find the results. They are all complimentary angles, that means if you sum the two equations representing the angles of each exercise they will be equal to 180º always
Step-by-step explanation:
3. notice 2x is complimentary of 2x + 80 because 2x is opposed to that blank space that compliments it.... I'm bad at explaining, I'll just show.
2x + 2x + 80 = 180
4x + 80 = 180
4x = 180 - 80
4x = 100
x = 25º
so then:
2x = 2*25
2x = 50º
and:
2x + 80 = 50 + 80
2x + 80 = 130º
I think not fpr sure though
Answer:
If it dilated by scale factor bigger than 1, is will getting bigger. So my answer is It is similar to Triangle ABC and has coordinate A'(8, -12), B'(4, -16), and C' (-20, 8).
Step-by-step explanation:
Answer:
s2 = 19 a=19 u1= 19√2 (26.87) u2= 19√2 (26.87)
Step-by-step explanation:
s2 - subtrace s1 from h to get 19
a - use the geometric mean of s1 and s2 (squre root of 19 times 19)
u1 and u2 - pythagorean thm
