Answer:
A
Step-by-step explanation:
If you rotate DEF 180 degrees it will look the same as ABC and the order is angle side angle because the side 5cm is between the 2 angles 57 and 40
Answer:
f(x)=|1/2x|
Step-by-step explanation:
Note that 500 ml = 0.5 liter. Comparing 0.50 liter and 0.75 liter is relatively simple.
Who drank more water?
Answer:
2.5
Step-by-step explanation: 1+3+0+6=10
10 divided by 4 is 2.5
Answer:
question 4 ... x = -11
question 5.... x = -7
question 6... x = 12
question 7.... x = 10
Step-by-step explanation:
<h2><u>number 4</u></h2>
note : the total angle of a triangle is 180 degrees
hence solve this by creating an equation
x + 51 + 60 + 80 = 180
x = 180 - 80 -60-51
<u>x = -11</u>
<h2><u>number 5</u></h2>
note : the total angle of a triangle is 180 degrees
hence solve this by creating an equation
remember that a <u>right angle is 90 degrees</u>
45 + 52+x + 90 = 180
x = 180 - 90 -52 -45
<u>x = -7</u>
<h2><u>number 6</u></h2>
note : the total angle of a triangle is 180 degrees
hence you can solve this by creating an equation
53 + 39+ 4+7x = 180
now make x the subject of the equation
7x = 180 - 53 - 39 - 4
7x = 84
x = 84/7
<h3><u><em>x = 12</em></u></h3><h3 /><h2><u>number 7</u></h2>
note : the total angle of a triangle is 180 degrees
hence solve this by creating an equation
6x - 5 + 5x + 75 = 180
now make x the subject of the equation
6x +5x = 180 - 75 + 5
11x = 110
x = 110/11
<h3><em><u>x= 10</u></em></h3>
