Answer:
143degrees
Step-by-step explanation:
sum of angles of a triangle =180degrees
let the third unknown angle be x
99+37+x=180
136+x=180
x=180-136
x=44
the sum of two opposite interior angles is equal to the exterior angle
44+99=<PQR
<PQR=143 degrees.
OR
the sum of angles on a straight line is 180 degrees
<PQR+37=180
<PQR=180-37
<PQR=143
Answer:
.22222222
Step-by-step explanation:
2/9 = 0.22222222
Answer:
no, it cannot
Step-by-step explanation:
a difference of square is: a² - b² = (a - b)(a + b)
looking at the expression (5z+3)(-5z-3), we see that it does not fit the criteria of the breakdown of a perfect square, as (-5z-3) has a negative <em>a</em> term (-5z)
if we FOILed (5z+3)(-5z-3) out, we would get:
-25z² - 30z - 9, which is not a difference of squares
1.Find a number both denominators can go into.Which is 16.
(What ever is done to the denominator must be applied to the numerator).
15*1/16*1 - 3*4/4*4
v
15/16 - 12/16
2. Subtract.
15 - 12 = 3/16
Answer: 3/16
Probability of any event = ( favourable outcomes ) /total number of outcomes
Probability of = 3/10 + 2/9 =
