The measures of the angles of a triangle are in the ratio 2:4:9 find the measures of all three angles
liraira [26]

all angles  = 180 degrees total

add the ratios: 2 +4 +9 = 15

180/ 15 = 12

12*2 = 24

12*4 = 48

12*9 = 108

108 + 48 + 24 = 180

the three angles are: 24, 48 and 108

The ordered pairs model an exponential growth function. (−1,21.875), (0,35), (1,56), (2,89.6) What is the function equation? f(x
Karolina [17]

Answer:

Given the ordered pairs, the exponential growth function would be represented by f(x)=35(1.6)^x.

Step-by-step explanation:

Exponential growth functions are represented by the following equation: f(x)=ab^x, where 'a'=initial value; 'b'=rate of growth; 'x'=independent value or time.  Given the points, we see that the values of 'x' increase by 1 each time and dividing two 'y' values (35/21.875; 56/35; 89.6/56) gives us a change of 1.6.  Rate is the change in y/the change in x, or 1.5/1, which is the value of 'b'. When 'x' is equal to 0, the value of 'y' is 35, so this represents the initial value, or 'a'.  Plugging in these values will give us the final equation f(x)=35(1.6)^x.

∠a and ∠b are complementary angles. ∠a measures 32੦. What is the measure of ∠b?
Ganezh [65]

Answer:

b = 58

Step-by-step explanation:

Complementary angles add to 90 degrees.

a+b = 90

32+b = 90

Subtract 32 from each side

32+b-32 = 90-32

b = 58
