Angle A= 88°
Angle C= 92°
Angle D= 80°
Step-by-step explanation:
Step 1:
From the basic property of Quadrilateral Angle A and Angle C are supplemental( Which means sum of Angle at A and Angle at C is equal to 180 degree)
Step 2:
From the given figure We could relate that
Angle at A = (X-2)°
Angle at C = (X+2)°
Angle at D = (X-10)°
(X-2)° + ( X+2)° = 180°
On simplification
X-2+X+2=180°
2X=180°
and X=180/2
X = 90°
Angle at A= (90-2)° = 88°
Angle at C = (90+2)° = 92°
Angle at D= (90-10)° = 80°
Answer:
The possible value for angle P will be 100
And sum will also 100 because it has only one value.
Step-by-step explanation:
Given:
angle R measures 40 degree and PQR is isosceles triangle.
To Find:
Measure angle P.
Solution:
The given triangle is isosceles hence it will have 2 same angle included in it.
And sum of all angles of a triangle is 180 degree.
let same angles be x and other be y
So ,
x+x+y=180.............. sum of all angles.
2x+y=180.
Now to find possible values for y ,with x=40,
2x+y=180
80+y=180
y=100
So being x= 40 y =100 which satisfy given angle R condition.
now let y=80,then x should satisfy 40 degree value, so
2x+80=180
2x=100
x=50
it doest not satisfy the given value hence possible for y will be 100.
Since x=40 degree.
Answer:
One is a set and another one is an ordered pair.
Step-by-step explanation:
Any set of numbers enclosed in curly brackets are considered sets while any two numbers enclosed by small brackets seperated by a comma are ordered pairs.
Step-by-step explanation:
an object and its shadow create a right-angled triangle.
2 objects and their shadows at the same time create therefore two similar right-angled triangular
triangles.
that means the angles are the same, and each side length of one triangle correlates to the corresponding side length of the other triangle by the same factor.
so, when we know the factor of one pair of sides, we can calculate the lengths of the others by using the same factor.
therefore,
1.57 × f = 50.5
f = 50.5 / 1.57 = 32.1656051...
the height of the tower is then
3.1 × f = 3.1 × 32.1656051... = 99.7133758... m ≈ 100 m
