Answer:
C
Step-by-step explanation:
Since XY = XZ = 6, then the triangle is isosceles.
The base angles are therefore congruent, that is
∠ Y = ∠ Z = 70°
The sum of the 3 angles in the triangle = 180°, thus
∠ X = 180° - (70 + 70)° = 180° - 140° = 40° → C
Well a ratio is a fraction but with a colon so 7/12 would be 7:12
R = 3
6x3=18
18x3=54
54x3=162 ...
Step-by-step explanation:
- The area of the blue square will always equal the sum of the area of the orange and red rectangles
The pythagorian theorem:
a²+b² = c²
now let a be the side of the red triangle and b the side of the orange one
so a² is the area of the red triangle and b² is the area of the orange one
Let c be the side of the blue rectangle
so c² is the area of it
then what we concluded is right
- the hypotenuse is the blue side since it is the larger one
