1. 30°
2.![1:1:\sqrt{2}](/tpl/images/1013/6742/36566.png)
3. 20cm
4. 5cm
Step-by-step explanation:
for the first one:
we have the triangle RVT and we know that
so![\angle T](/tpl/images/1013/6742/73b51.png)
= 180
so
for the second one
we know by specials right triangles that the sides are
divide by x and get
for the third one
again by 30-60-90 triangle we know that
for the fourth one
here we can use excersie 3 and the ratio of XY:YC = 1:1
that means they are equal so
XY=YC
XY = 5
Ответ:
➷ You have to collect like terms
In other words, add together the values that have x in them and add together the values that don't
4x + 7x = 11x
8 + 3 = 11
The answer is 11x + 11
✽➶ Hope This Helps You!
➶ Good Luck (:
➶ Have A Great Day ^-^
