<h3>Answer: 5% growth (fourth choice)</h3>

the base of the exponent 1.05 is in the form 1+r

1+r = 1.05 which solves to r = 0.05 when we subtract 1 from both sides

Since r is positive, it represents growth.

0.05 = 5/100 = 5%

Find the measure of the largest angle in ABC if a = 12, b = 8 and c = 13.

Papessa [141]

Answer:

$C=78.28^{\circ \:}$

Step-by-step explanation:

We are given a triangle

whose sides are

a=12

b=8

c=13

Since, c is largest among them

So, angle C must be largest angle

we can find angle C

we can use law of cosine formula

$cos(C)=\frac{a^2+b^2-c^2}{2ab}$

now, we can plug values

$cos(C)=\frac{12^2+8^2-13^2}{2\times 12\times 8}$

$cos(C)=\frac{13}{64}$

now, we can find angle

we get

$C=78.28^{\circ \:}$

tomas is thinking of a number. If he triples his number and subtracts 13 the result is 305. Of what number is tomas thinking

dezoksy [38]

3x-13=305

3x=305+13

3x=318

(3x)÷3=318÷3

x=106

check.. (3×106)-13=305

318-13=305

305=305
