Can someone help if you could that would mean so much to me

A) 6 square meters

Step-by-step explanation:

To find the area of a triangle you must multiple the base and the height, but in this question the base isn't given. Using the Pythagorean theorem to find the base you get 4 as the base. Now you multiply 3 and 4 to get 12 (square area), then divide it by two and get 6 (triangle area)

Steps:

b^2 = 5^2 - 3^2

b^2 = 16

3*4 = 12

12/2 = 6 square meters

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
