753,249 - 575,388 = 159,861
i hope it's right :)
Answer:
Therefore the triangles are congruent by Angle Angle similarity postulate.
ΔEFG ~ ΔHJK ...{ By Angle-Angle similarity postulate}
Step-by-step explanation:
Given:
In right triangle ΔEFG
m∠E= 25°.
In right triangle ΔHJK,
m∠H=25º
To Prove:
ΔEFG ~ ΔHJK
Proof:
In right triangle ΔEFG and ΔHJK
m∠ E ≅ m∠ H .......{measure of each angle is 25° given}
m∠ F ≅ m∠ J .........{Both triangle is Right angle Triangle therefore measure angle is 90° each}
∴ ΔEFG ~ ΔHJK ...{ By Angle-Angle similarity postulate}
Therefore the triangles are congruent by Angle Angle similarity postulate.
ΔEFG ~ ΔHJK ...{ By Angle-Angle similarity postulate}
I think the answer is c) 4,1 .
Answer:
72 in²
Step-by-step explanation:
lateral area: the surface area of a 3D figure, but excluding the area of any bases
the lateral area of this prism is the sum of the three rectangular sides.
calculate the third side of the triangle first because it's also the side of one of the rectangle:
√(5² - 4²) = 3
4 × 6 + 5 × 6 + 3 × 6 = 72
Using the distance formula, you can determine the lengths of the sides of the shape. This will help determine if triangles are equilateral, isosceles or scalene; or if quadrilaterals are squares, rectangles, rhombi, or isosceles trapezoids; or if other polygons are regular polygons. The slope formula will tell help you determine if two sides are parallel. In a quadrilateral, this will help you determine if the figure is a parallelogram or a trapezoid.
