Answer:
137°
Step-by-step explanation:
All angles in a triangle add up to 180° always.
Now imagine the two smaller shapes as a bigger triangle, CED. The measure of angle CED is 89°, and CDE is 48°. Do the math, and angle DCE is 43°.
But notice how the corresponding sides of the two smaller shapes are congruent. (CX=XE, and DY=YE) Meaning, the measure of angle C is equal to the measure of angle YXE.
We're almost there. CXY (what we're looking for) and YXE are supplementary angles, meaning the angle measures add up to 180. 180-43 = 137°.
Answer:
Substitution Property of Equality
Step-by-step explanation:
The substitution property of equality states that if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.
In this case, m∠A + m∠B in the second equation is substituted by 88°, from the first equation. This allows as to find m∠C as follows:
88° + m∠C = 150°
m∠C = 150° - 88° = 62°
Saturn is 1.4 times 10^9, while Venus is 1.1 times 10^8.
Saturn- 1.4 times 1,000,000,000= 1,400,000,000
Venus- 1.1 times 100,000,000= 110,000,000
You can see that Saturn is further away from this, and now all you have to do is subtract Venus' distance from Saturn's.
1,400,000,000-110,000,000
=1,290,000,000
Now you need to put this in scientific notation.
1.29 times 10^9
Answer:
The other side would be 3ft and the bottom would be 1ft I believe.
