Answer:
minus 9, and 1
Step-by-step explanation:
Answer:
18.2
Step-by-step explanation:
JK is the side perpendicular to the horizontal (JL) thus it is opposite to angle 55°. JL is the adjacent, therefore, we can use the trigonometric ratio Tangent to fins the adjacent.
Tan ∅= opposite/ adjacent
Adjacent = opposite/Tan ∅
Adjacent =26/ Tan 55°
=18.2
Answer:
7
Step-by-step explanation:
7 shows up twice
all other numbers show up only once.
Let the third angle of the triangle be y.
y + 64° + 45° = 180° (angle sum of triangle is 180°)
x + y = 180° (angle of a straight line is 180°)
Notice that they both equal 180°. This means that they are the same thing, hence:
y + 64° + 45° = x + y
Since y = y, it is not necessary to write them down. Remove y from both sides of the equation:
64° + 45° = x
Surprise! exterior angle = sum of interior opposite angles.
