Answer:
1) <DHG = 94 degrees
2) <3 = 29 degrees
3) <1 = 47 degrees
4) <5 = 78 degrees
5) <4 = 60 degrees
Step-by-step explanation:
1). 2a -3 = 4a -10 (vertical angles)
- 3 + 10 = 4a - 2a
7 = 2a
a = 7/2
<5 = 2(7/2) - 3 = 4 degrees and <3 = 4(7/2) - 10 = 4 degrees
<DHG = 90+4 = 94 degrees
2). 4p+5+2p+1 90 (complementary angles)
6p+6 = 90
6p = 90-6
p = 84/6
p = 14
<1 = 61 degrees and <5 = 29 degrees
<3 = 29 degrees
3). 4w - 13 + 2w + 18 = 90 (complementary angles)
6w + 6 =90
6w = 90-6
W = 14
m<BHC = 4(14) - 3 = 53 and m<DHC = 2(14)+19 = 47
<1 = 47 degrees
4). <1 = <4 (vertical angles)
2d+7=3d-15
7+15 = 3d-2d
d = 22
<1 = 2(22)+7=51 and <4 = 3(22)-15=51
<5 = 180 - 102 = 78 degrees
5). 5r + 20 + 3r = 180
8r = 180 - 20
r = 160/8
r = 20
<AHB = (3)(20) = 60
<AHF = 180-60 = 120
<AHG = 120/2 = 60
<AHG = <4 (vertical angles = 60 degrees
2 is the answer as ‘quotient’ means the number divided by the other number.
Answer:
3
Step-by-step explanation:
2 1/2 / 5/6
= 5/2 / 5/6
= 5/2 * 6/5
= 6/2
= 3
