Answer:
70*
Step-by-step explanation:
we have a right triangle - r is 90*
based on geometric rules: angle RPQ = 20 40 : 2
90 + 20 = 110
110 + x = 180
triangle have 180*
it means that 180 - 110 =
70 *
last answer D
Answer:
12.5%
Step-by-step explanation:
[First Value – Second Value] ÷ [(First Value + Second Value) ÷ 2] × 100
[50 - 30] ÷ [ 50 + 30] ÷ 2 × 100
20 ÷ 80 ÷ 2 × 100
0.25 ÷ 2 × 100
0.125 × 100
12.5 %
82=100%
100%-13%=87%
find 87% of 82
percent mean sparts ou tof 100
87%=87/100=0.87
'of' means multipy
87% of 82=
0.87 times 82=71.34
