What is the measure of angle A?
fgiga [73]

Answer:

∠A=65º

Step-by-step explanation:

  • A angle of a line is 180º, so we can say that angle ABC=(180-6x)º
  • The interior angkes of a triangle is 180º, so (x+40)º+(3x+10)º+(180-6x)º=180º
  • Remove parenthesis, x+40+3x+10+180-6x=180
  • Combine like terms, -2x+230=180
  • Subtract 180, -2x=-50
  • Divide by -2, so x=25

Now:

  • ∠CAB=(25+40)º=65º
  • ∠ABC=[180-6(25)]º=30º
  • ∠BCA=[3(25)+10]=85º

Please help idk thisssss
Alekssandra [29.7K]
ANSWER
0.073 \% = 0.00073


EXPLANATION

Recall that,

\% =  \frac{1}{100}


That is why
100\%
is equivalent to
1.





This implies that,


0.073\% = 0.073 \times  \frac{1}{100}






This is the same as,


0.073\% = \frac{0.073}{100}


When we are dividing by
100
we move the decimal point backwards two times.


This implies that,

0.073\% = 0.00073

Alexus [3.1K]

Answer: $110


Step-by-step explanation:

Given: At Simba Travel Agency, the price of a climbing trip to Mount Kilimanjaro includes an initial fee plus a constant fee per meter.

F(d)models the fee (in dollars) for climbing d meters.

F(d)=110+0.12d

To find the initial amount, substitute d=0 int the above function, we get

F(0)=110+0.12(0)=110


Hence, the initial fee= $110.
