vazorg [7]

Answer:

23 inches

Step-by-step explanation:

assuming that the desktop screen is a rectangle, then it's diagonal will form two right triangles.

by the Pythagorean theorem

${a}^{2} + {b}^{2} = {c}^{2} \\ a = 14 \: and \: b = 18 \\ c = the \: hypoteneuse$

then

${14}^{2} + {18}^{2} = {c}^{2} \\ 196 + 324 = {c}^{2} \\ 520 = {c}^{2} \\ \sqrt{ {c}^{2} } = \sqrt{520} \\ c \: \: is \: a pprox. \: \: 22.8 in \\ c \: \: rounded \: is \: 23in$

Answer:

side c = 10.2

A = 52.6°

B = 37.4°

Step-by-step explanation:

c² = 8.1² + 6.2²

c² = 104.05

c = 10.20049018

Using cosine law:

8.1² = 10.2² + 6.2² - 2(10.2)(6.2)cos

cosA = 7687/11648

A = 52.57199409

A = 52.6°

B = 180 - 90 - 52.6 = 37.4°
