If the two triangles are congruent, you can just look at both triangles and see what is missing from each. They are all the same! :D
z = 10 yd
v = 7.9 yd
y = 38°
u = 6.2 yd
x = 90°
And to find w...
You know that the sum of all angles in every triangle is 180°. We know that two angles are 38° and 90°. Add them and subtract it from 180° to find the remaining angle.
90 + 38 = 128
180 - 128 = 52
So w = 52°
Hope this helps! :D
Answer: The answer is 6.
The number sentence is
3-3=0
10-4=6
So, 13-7=6
Step-by-step explanation:
To solve , by making ten
First break 13 and write
Then break 7 as
Now to subtract 7 from 13,
Step 1. Subtract 3 (a part of 7), from 3(a part of 13) or cross 3 circles, then we have left 10-4
Step 2. Subtract 4 from 10 or cross 4 circles out of 10, we get 6.
The answer is 6.
1.
-2(a + 6) = -2 · a - 2 · 6 = -2a - 12
2.
-22:
whole numbers
rational numbers
integers
3.
6 · (b - p) = 6(b - p)
4.
[5(14 - 2)²]/2 = (5 · 12²)/2 = (5 · 144)/2 = 720/2 = 360
5.
u + xy
u = 18; x = 10; y = 8, subtitute
18 + 10 · 8 = 18 + 80 = 98
6.
A = 479 ft²;
a - length of a side
A = a²
therefore
a² = 479 ⇒ a = √479 ⇒ a ≈ 21.886 ⇒ 22 (ft)
7.
(7 + 5) + 4 · 13 - 2 = 12 + 52 - 2 = 64 - 2 = 62

Answer:
D: 10a+10 ; 5(2a+2)
Step-by-step explanation:
25+3(a-5)+7a
= 25+3a-15+7a
=10+10a
