Answer:
140
Step-by-step explanation:
<u>As per picture:</u>
∠PTQ and ∠RTS are vertical angles and they are equal
- ∠PTQ = (x + 28)°
- ∠RTS = (2x + 16)°
- ∠PTQ = ∠RTS
- x + 28 = 2x + 16
- 2x - x = 28 - 16
- x = 12
∠PTR is supplementary with ∠PTQ and their sum is 180°
- ∠PTQ = 12 + 28 = 40°
- ∠PTR = 180 - 40 = 140°
Answer:
b=18
a=6√18
Step-by-step explanation:
tan 45=b/18
by cross multiply
b=tan 45×18
=1×18
=18
find (a) by using pythagora's theorem
a^2=18^2+18^2
=324+324
a^2=648
take square root both sides
√a^2=√648
a=√36×18
a=6√18
5/8=0.625
7/12=0.583......
5/8 is bigger as ive put both into a decimal as it is easier to tell
Answer:

because i aint never seen two pretty best friends, its always one of em gotta be ugly
With the given data, the first step to take is to use MS excel to plot the data then determine the trendline in which the equation's r2 value is closest to 1. From the plot obtained from Excel, the plot is a second degree polynomial and not an exponential function. the answer hence is no.
