Answer:
Right triangle
Step-by-step explanation:
7^2 + 6^2 = c^2
49 + 36 = c^2
85 = c^2
c = 9.22
Answer:
D..... 3 lines of Symmetry
77. 0.205 < 0.21
It's less by 0.005
78. 0.1 = 0.1000
The extra zeroes do not change the solution.
79. -0.04 > -0.050
While this might look greater, remember to check the number line position
80. -1.03 < -0.03
Same as the last one.
81.

< 0.6

= 0.5 < 0.6
82. -

< -0.03
Same process as 80 mixed with 81.
I hope that these help.
Answer:
PB = 1.8
Step-by-step explanation:
PQ = 8 cm, BC = 10 cm and AB = 9 cm
∆ABC is similar to ∆APQ.
Therefore:

Plug in the values

Cross multiply
AP × 10 = 8 × 9
AP × 10 = 72
Divide both sides by 10
AP = 7.2
PB = AB - AP
PB = 9 - 7.2
PB = 1.8
