Answer:
a) ∠DAE = 33°; ∠ABD = 57°
b) ∠CEB = 90°
c) ∠ABE = 22°
d) ∠ADE = 15°
Step-by-step explanation:
The diagonals of a rhombus meet at right angles. Each bisects the corner angles at its ends. Adjacent angles are supplementary, opposite angles are congruent, and each diagonal creates two isosceles triangles.
a) ∠DAE = 90° - ∠ADE = 90° -57°
∠DAE = 33°
∠ADE = ∠ABD = 57°
__
b) ∠CEB = 90° . . . . . the diagonals meet at right angles
__
c) ∠ABE = 44°/2
∠ABE = 22°
__
d) ∠ADE = 90° -(1/2)∠DAB = 90° -150°/2
∠ADE = 15°

Step-by-step explanation:
<u><em>The correct question is</em></u>
1x10 to the fifth power over 4x10 to the negative fourth power given on scientific notation
we know that
To divide two numbers in scientific notation, divide their coefficients and subtract their exponents.
we have
Answer:
He pays $8.70
Step-by-step explanation:
You would do $67.86 divided by 7.8 lbs
Answer:
9 cups
Step-by-step explanation:
If one pound is equal to 2 cups, then you would multiply 2 by 4, which gives you 8. If one pound equals 2 cups, then half a pound equals 1 cup. So since we already have 8 cups, you just add one more cup, which gives you 9 cups total
SUMMARY: You can expect to get 9 cups of grated parmesan cheese from a 4.5-pound block.
The third side of the triangle is 26.
Explanation:
Given:
Two sides of the isosceles triangle are 26 and 10.
To Find:
The possible value of the third side
Solution:
Definition of Isosceles triangle:
An isosceles triangle is a triangle with (at least) two equal sides. Isosceles triangle has both two equal sides and two equal angles.
We also know the property of the triangle that
Sum of two sides of triangle > third side of the triangle
Case1. When third side is 10
Thee third side can’t be equal to 10 because it does not follow the rule of triangle
10+10>26………which is not possible
So the third side of the isosceles triangle is 26.
