Answer:
area = 13.8 cm²
Explanation:
The area of the triangle can be calculated using the following rule:
area of triangle = (1/2) * base * height
In the given:
base of triangle = 6.9 cm
height of triangle = 4 cm
Substitute with the givens in the above equation to get the area as follows:
Area = (1/2) * (6.9) * (4)
Area = 13.8 cm²

Answer:
15% increased
=16% increased
=17% invreased
Step-by-step explanation:
The equation is AN=A1+D(N-1) A1 being the first number (2) D being the difference (in this case 5) and N being the nth term to find (34) so here you have AN=2+5(34-1) then AN=2+5(33). the answer here is 167.
So to solve for x, you'll need to combine all the angles and equal it to 720, and from there we can solve.
Combine like terms to get
Subtract 470 on each side to get
Then just divide on each side and you'll get
To find the value of the (x+10) angle, just substitute 125 for x and solve.
