Find all the missing angles: a, b, c, d.

Mathematics

morpeh [17]3 years ago

Answer:

a= 180-60-55=65

we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a.

b=180-90-65=25

the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b.  

c=25

c is 25, because two angles on both sides of a X is the same

Between x = 2 and x = 3, which function has a smaller average rate of change than y = 2x ? A) y = 2 3 -x B) y = 4x - 1 C) y = 5x
xxTIMURxx [149]
The two points are (x, f(x)) and (x+h, f(x+h)).  To find the slope, the definition is the change in y over the change of x.  Does this sound familiar!!  Applying this definition we get the following formula:  and the points x<span>1 = 2 and x2 = 4.  Then in our general answer, we will replace x with x1 and h = x2 - x1.  Replacing these values in the formula yields  2(2) + (4 - 2) = 4 + 2 = 6.  Thus, the slope of the secant line connecting the two points of the function is 6. </span><span>Now using the same function as above, find the average rate of change between x1 = -1 and x2<span> = -3.  The answer is 2(-1) + ( -3 + 1) = -2 + -2 = -4.  This means that the secant line is going downhill or decreasing as you look at it from le</span></span>

Find the area of a right triangle with side lengths 12 cm, 35 cm, and 37cm
Maurinko [17]

Answer:

210 cm sq

Step-by-step explanation:

Area of a triangle is 1/2bh.

12 cm and 35 cm would be both sides of the triangle, not 37 cm because it is the hypotenuse (largest side).

1/2*12*35=210 cm sq

An ostrich that is 180 inches tall is 20 inches taller than 4 times the height of a kiwi. what is the height of a kiwi in inches
butalik [34]
Let's call the weight of an ostrich o=180.

we know that o=20+4*k, or, if we substitute o for 180: 180=20+4*k

where k is the weight of a kiwi.

if we want to know k, we have to subtract 20 from both sides of the equation first:

160=4*k

and divide them by 4:

40=k

So a kiwi is 40 inches high.
