Answer:
≈ 50.7 cm²
Step-by-step explanation:
The area (A) of Δ XYZ is calculated as
A = 
bh ( b is the base and h the perpendicular height ), that is
A = × XY × YZ
Calculate YZ using the tangent ratio in the right triangle
tan40° = 
= 
= 
( multiply both sides by 11 )
11 × tan40° = x , that is
YZ ≈ 9.23 cm
Thus
A = × 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )
Answer:
7x(3 13)
Step-by-step explanation:
70 millimeters are in 7 centimeters since 10 millimeters is equal to one centimeter you would multiply 7 centimeters times 10 millimeters and get 70
False.
You are rounding to the nearest tenth place. With your decimal value, 3 < 5, so therefore you cannot round the 4 up to 5. Given this, your correct decimal rounded to the nearest tenth = 16.400
First plug in -4 for g to get 3(-4)-1. 3(-4) equals -12, and -12-1 equals -13.
