Answer:
122.5 cm²
Step-by-step explanation:
Area of this trapezium:
1/2 × 35 × 7
= 245/2 = 122.5 cm²
Find A <span>if B is between A and C.
</span><span>A.B,and C are collinear so A, B and C are line up in a line</span>
AC = AB + BC
AB=5x-19,and BC= 3x+4 given;
So
AC = 5x-19 + 3x+4
Simplify
AC = 8x -15
Step-by-step explanation:
First calculate your percent as: 1-0.38=0.62. Then, multiply 0.62 by 50= 31. Your answer is 31
Answer:
<u>x = 120°, y = 20°</u>
Step-by-step explanation:
Let's recall that the four interior angles in any rhombus must have a sum of 360 degrees. In addition, the opposite interior angles must be equivalent, and the adjacent angles have a sum of 180 degrees.
∠ ABC and ∠ ADC are opposite interior angles, so they must have equivalent measurements, therefore x = 120 degrees.
To find the value of y, we use this equation because the interior angles of the Δ ADC add up to 180:
y = 180 - 120 - 40
y = 180 - 160
y = 20 degrees ⇒ z = 40 degrees
