Answer:
∠ABC=90°
Step-by-step explanation:
if ∠DAB =110 then ∠BAC =180-110 =70° because straighht lines make 180°∠s
use the fact that the sum of angles in a Δ is 180°
∠ABC= 180-20-70= 90
Answer:
180 square inches
Step-by-step explanation:
Area, A is given by A=0.5bh where b is base and h is height. Since both of these dimensions are provided then we substitute the given figures into the formula. Substituting 12 inches for base, b and 30 inches for height, h then the area will be equivalent to
A=0.5*12*30=180 square inches.
Therefore, the area of the described triangle is 180 square inches.
3.48 x 10^ -5
move the decimal point back to the first number that isn't zero, if the decimal is moved right 5 spaces, it will be 10^ -5 , if a number has a zero, such as 0.000104, it would be 1.04 x 10^ -4.
