Solve the right triangle shown in the figure. BC = 2.7cm, AC = 1.1cm, ZC = 90°
a. ZA = 689, ZB = 220, AB = 2.9cm
b.
ZA = 22°, ZB = 689, AB = 2.9cm
C. ZA = 630, ZB = 27°, AB = 2.9cm
d. ZA = 240, ZB = 66°, AB = 3.8cm

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
