Answer:
Using the Angle Addition Postulate, 15 + 40 = m∠ABC. So, m∠ABC = 55° after simplifying.
Step-by-step explanation:
The Angle Addition Postulate is gotten from angles placed side by side to form a resulting angle that is the sum of all the individual angles.
If D is the interior of ABC then, ABC is split into two parts i.e ABD and DBC, then the measure of ABC is the sum of the individual two parts
m∠ABC = m∠ABD + m∠DBC.
Using the Angle Addition Postulate:
m∠ABC = m∠ABD + m∠DBC
m∠ABC = 15 + 40 = 55°
m∠ABC = 55°

Answer:
BC=EC(GIVEN)
AC=DC(GIVEN)
<BCA=<DCE(VERTICAL OPPOSITE ANGLE)
BCA=DCE(BY SAS CRITERIA)
BA=DE(BY CPCT )
2632 I think because 624 minus 3256 equals 2632 before finances

Explanation:
Angle = 67°
To solve the question, we will use an illustration:
To get the horizontal distance from the base of the skycrapper to the ship, we will apply tangent ratio:
opposite = 903 ft
adjacent = horizontal distance from the base of the skycrapper to the ship = x
To the nerest hundredth, the horizontal distance from the base of the skycrapper to the ship is 383.30ft
