Find the area of the following
pls

A = 70 m²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 14 and h = 10 , then

A = × 14 × 10 = 7 × 10 = 70 m²

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
