Answer:
137
Step-by-step explanation:
The sum of all three angles; <ABC, <ABD, and <CBD is equal to 360
now we know <ABC = 118 and
the measure of central angle <CBD is equal to measure of the arc it sees so it's = 105
we are asked to find the m<ABD
118 + 105 + <ABD = 360 add like terms
223 + <ABD = 360 subtract 223 from both sides
m<ABD = 137
Answer:
square root of 7
Step-by-step explanation:
Each right angle triangle has 3 sides known as the opposite, adjacent and hypotenuse sides. The relationship between these 3 sides is as defined by pythagoras theorem which states that
a² + b² = c²
where a and b are the lengths of the opposite and adjacent sides (in no particular order) and c is the length of the hypotenuse side.
Given that the leg of a right triangle is 3 units and the hypotenuse is 4 units, it means that
a² + 3² = 4
where a is the length in units, of the other leg of the triangle
a² = 4² - 3
a² = 16 - 9
= 7
a = √7
