Answer:
Aplha=105
Step-by-step explanation:
The perpendicular looks like double the base hence that angle is 30 and the other triangle have equal perpendicular and base, that angle is 45. So alpha+30+45=180, alpha=105
5x-2+x=9+3x+10
6x-2=3x+19
3x=21
x=21/3
x=7
I would say choice C with 4 is the right ones
Answer:-11/32
Step-by-step explanation:
-7/8 - (-17/32)
= -7/8 + 17/32
The highest common factor is 32
= (-7*4+17)/32
= (-28+17)/32
= -11/32
Percent change=change/original times 100
change=75 to 25 or 75-25=50
so
percent change=50/75 times 100=0.6666666 times 100=66.66666%
tenth
66.7%
